Deadwood doesn’t grow overnight.

TERWAKELO DOESN’T SHOUT.
IT IS JUST THERE.

TERWAKELO is a phone case made from genuine Nordic birch, tar-treated to a grayish finish. The tone recalls deadwood — old timber that has stood for years, the silence of the northern forest. No shine. No fuss. No mass production.

01

Spirit of deadwood. No copy.

Each wooden phone case is made from genuine Nordic birch. The grayish tar treatment makes every piece unique — mass production can’t do this.

02

Oulu. Tar tradition.

Lastu was born in Oulu — the historic tar city. TERWAKELO is a more understated take on that heritage: drier, smokier, calmer.

03

MagSafe. Engraving. You.

Choose MagSafe compatibility or add your own engraving — symbol, coordinates, name, animal figure. The live preview shows the final result before you order.

No stock.
Made in the Nordics, to order.

Each TERWAKELO phone case is made to order from Nordic birch. The grayish tone comes from the combined effect of the tar treatment and the wood’s natural aging. When you pick up your phone, you feel real wood — not cold plastic.

Tar A restrained tar scent — smoky and calm. No stickiness, no staining.
MagSafe Available for all phone models on the product page. Wireless charging and magnetic accessories work at full power.
Engraving Symbol, animal, coordinates, logo, or name. In the preview, the engraving appears in black — on the finished phone case, it’s the natural tone of the wood.
Live preview Phone model, material, MagSafe, and personalization — everything updates in real time before you order.

Materials & protection


Lastu's phone cases are mainly made from genuine Nordic birch, finished in Oulu in several shades:
Hiili, Lumi, Rosa and natural birch.
Each phone case has a unique surface pattern – the birch grain lives and changes with the light, so you won't find two identical pieces.


We also offer special editions using genuine military-grade fabrics, such as
M05, M90, Flecktarn and MM14.
These cases feel more technical and deliver top-tier abrasion resistance.

Frame & fit


A flexible, shock-absorbing TPU frame combines with the chosen surface material to make the case light yet snug.
1 mm raised lip helps keep the camera and screen off the table during everyday bumps.

  • Feel: thin, lightweight and grippy
  • Fit: snug, precise button and cutout alignment
  • Protection: SGS-lab verified MIL-STD-810H 516.8 drop test (2 m, corners)

MagSafe & wireless charging


An optional embedded neodymium ring makes the case MagSafe-compatible for many models like
iPhone, Samsung, Google Pixel, OnePlus and Nothing.

MagSafe cases keep accessories — like wallets and the KRIP 2.0 finger grip — firmly in place.
Cases also work with Qi wireless chargers, so charging is effortless.

Compatibility & finish


Port and speaker cutouts, camera frames and button alignment are carefully executed so phone cases and covers fit precisely without any play.
A matte-black TPU rim improves grip and gives the whole a polished, confident look.

Manufacture & delivery


All Lastu cases and covers are made to order in Oulu.
Products are produced within 2–8 business days and shipped with your chosen delivery method.
Free shipping available. Delivery times are shown at checkout.

In a nutshell


Genuine Nordic birch + flexible TPU frame + 2 m drop test + (optional) MagSafe =
a lightweight, durable and uniquely personal everyday shield.

These protective cases and phone cases are made for you — as a gift, for daily use, and to make your phone truly yours.

A MAGNET THAT CHANGES EVERYTHING

MagSafe is a magnetic mounting system based on a magnetic ring installed inside the phone case. Accessories attach precisely, securely, and without compromises.

What is MagSafe used for?

Finger grip
Secure hold without glue
Wallet
Attaches and detaches in an instant
Stand
Works with magnets, no mechanical locks
Wireless charging
Snaps automatically into the right spot
An important thing many people don’t know

MagSafe accessories do not work without a MagSafe magnet. Even if the phone model is the same, the accessory won’t stick if the phone case doesn’t have MagSafe.

Does MagSafe only work on iPhone?

No. Lastu MagSafe also works with other brands.

Samsung
OnePlus
Google Pixel
Nothing
iPhone
+ other models

The phone brand is not what matters. What matters is that the phone case includes a properly placed magnet. Lastu adds MagSafe to any phone case.

Compatible with all MagSafe accessories

Lastu’s MagSafe feature is designed to work with all MagSafe accessories on the market — not just Lastu’s own. When you choose MagSafe for your phone case, you unlock an entire ecosystem.

Chargers
MagSafe chargers and charging stations snap into place automatically
Car mounts
Magnetic car mounts — attach and detach with one hand
Finger grips
PopSockets, finger rings, and other MagSafe holders without glue
Wallets
Card wallets attach to the back — remove them when you don’t need them
Desk stands
Magnetic mounts for home and office — your phone stays in place
Power banks
MagSafe batteries attach to the back of the phone for wireless charging on the go
In practice

One MagSafe phone case — all accessories fit. Switch from a finger grip to a wallet during the day, then to a car mount at night. The attachment always feels the same: precise, solid, secure.

Compatibility note

On certain Samsung, OnePlus, and Nothing models, the magnet is placed slightly lower because of the camera size. Accessories work normally, but wireless MagSafe charging may not work.

This does not apply to iPhone or Google Pixel models.

In short

MagSafe = a magnetic ring inside the phone case.

Without it, accessories won’t stick.

Lastu adds MagSafe to any phone case — no matter the brand.

On average, 96 times a day. Your finger glides across it. The screen is your phone’s most touched surface — and yet most people leave it bare.

PROTECT WHAT YOU USE

LEKA is a nano-PET screen protector designed by Lastu. 0.38 mm thin. Fully clear. A glass-like feel that blends seamlessly with the phone’s own screen.

No haze. No clunky feel. No interference with the touchscreen.

Invisible. On purpose.

LEKA doesn’t change your phone. It protects the screen from scratches and wear so well you’ll forget it’s there — until you look at your old phone and notice the difference.

The NANO-PET surface keeps the screen bright and natural. The UV coating adds invisible protection. The design is sized to work with all phone cases so the protection extends evenly across the entire screen.

KRIP 2.0 MagSafe ring holder – aluminum MagSafe accessory for Lastu cases

KRIP 2.0 – THE MAGSAFE RING HOLDER THAT STAYS PUT

Better grip, more stable support, and the freedom to swap accessories as needed. Aluminum construction, strong magnetic attachment, and a carefully sized ring — in hand, on the table, and on the move.

Material
High-quality aluminum
Durability
10 000 fold cycles
Attachment
MagSafe magnet
Removal
Slide sideways

Stronger hold in Lastu’s MagSafe-compatible cases

KRIP 2.0 works especially well with Lastu’s MagSafe-compatible cases. In Lastu cases, the MagSafe magnet sits right at the surface, not inside the structure. That means significantly stronger magnetic hold — the ring holder stays firmly in place without extra force.

Easy to use, secure grip

A spacious, comfortable finger ring. Makes one-handed browsing easier. Reduces the risk of drops in everyday use — especially with larger phones.

Stand for portrait and landscape mode

The ring holder also works as a sturdy stand. Your phone stays steady in both positions.

Video calls
Hands-free, steady shots
Photography
A secure grip and a stand
Recipes
Phone upright in the kitchen

Why KRIP 2.0 instead of a fixed ring holder?

Fixed holder
Blocks wireless charging. Locks you into one setup.
KRIP 2.0
Wireless charging works. Swap the ring holder, wallet, or just the case.
Proper removal

KRIP 2.0 is removed by sliding it sideways, not pulling it straight off. This keeps unnecessary strain off the magnet and helps the attachment last longer.

Strong attachment in Lastu cases

MagSafe magnetic card wallet in Lastu cases

KARB works especially well with Lastu’s MagSafe-compatible phone cases. In Lastu’s cases, the MagSafe magnet sits right at the surface of the case — not buried inside the structure. This improves grip and makes the attachment more secure compared with many other MagSafe solutions.

In practice

The wallet stays in place in everyday use, but it’s easy to remove when you want to use your phone without extras. Wireless charging works when the wallet is removed.

Freedom to switch as needed

Unlike fixed adhesive card pockets, KARB does not lock your phone into one way of using it.

Option 1
Card wallet attached — bring your cards along
Option 2
Finger grip attached — better hold
Option 3
Just the case — light and clean
Option 4
Nothing — wireless charging works

Correct removal

Important

KARB is removed by sliding it to the side, not by pulling it straight off. This avoids unnecessary stress on the magnet and helps the attachment last longer.

Frequently Asked Questions

Both are made from genuine Nordic tarred birch. TERWA has a darker, stronger tone — a deep tar scent and bold contrast. KELO is lighter and more understated: the tar is lighter, the tone closer to nature. Choose based on your mood.

KELO stands apart from an ordinary birch phone case with its unique surface treatment: tar brings depth to the wood, a natural scent, and better resistance to moisture. Not a cheap mass-produced item - a Nordic material, made to order.

Absolutely. Tar is part of Finnish sauna culture and natural heritage. KELO is a meaningful and rare gift for someone who appreciates authentic natural materials.

Yes, MagSafe-compatible available. iPhone, Samsung Galaxy, OnePlus, Google Pixel and Nothing Phone. Made to order in Oulu, production time 2–8 business days.
