HIILI – black wooden phone cases & protective phone cases
made from real charred birch | iPhone, Samsung, OnePlus, Pixel, Realme

The campfire has burned down, but the embers still glow. That color is now in your hand. HIILI is a black wooden phone case made from real Nordic birch – the black goes into the wood, not sprayed on top. No plastic, no printed wood pattern, no same-old black Case that every other person already has. The grain lives under the darkness, so no two protective phone cases are alike – we do not even try. Fits iPhone 17, 16, 15, 14, 13, Samsung Galaxy, OnePlus, Google Pixel and Realme models. Choose MagSafe, engrave a name or add your own image.

Choose your phone model, color, MagSafe compatibility and, if you like, engraving, your own image or logo. The live preview shows your choices before you order. Fits iPhone, Samsung, OnePlus, Google Pixel and Realme phones.

This is a wooden protective phone case for you if you want a black case without that mass-produced feel. Made to order in the Nordics – not pulled from a shelf.

Material: real birch, multiple shades

  • Charcoal – fully charcoal-black birch with the wood grain visible. A unique black wooden phone case.
  • Snow – a light wooden phone case made from natural birch. Clean, calm and real.
  • Rosa – warm pink birch with the wood’s natural structure left visible.

Birch feels different in your hand than plastic: warm, light, a little like the spine of a hardcover book. Every wooden protective phone case is its own piece – the grain is the wood’s fingerprint.

Structure and protection

+ Textured edge profile – birch knows how to hold on. The wooden protective phone case stays in your grip even with gloves on, and does not slide off the table like glossy plastic.
The textured edge profile of the Hiilikoivu protective case gives a secure grip – the black wooden phone case stays firmly in your hand
+ Raised edge protects the screen – you can place the phone face down without the screen touching the surface. Read more about protection →
The Hiilikoivu case has a raised edge that protects the phone screen – the glass does not touch the table
+ Raised camera frame – the lens does not touch the table. The camera is better protected from everyday scratches and knocks.
The raised camera frame of the Hiilikoivu wooden protective case protects the lenses from scratches
+ Slim and lightweight build – birch does not bulk up your phone in your pocket, but in the hand it feels on a whole other level than a plastic case.
+ MagSafe compatibility available – wireless charging, magnetic mounts, finger grips and wallets work firmly when you choose the MagSafe version.
+ Laser engraving, your own image or logo – a name, initials, company logo, symbol or your own image. The live preview shows the result before you order. See the design guide →

Not from stock. From the Nordics, made to order.

Black birch. Not black plastic.

Every Hiilikoivu protective case is made to order from Nordic birch. Lastu’s own coloring process takes the black deep into the wood, while leaving the grain visible – that is why the case is black in a different way every time. This is a protective phone case that looks black but feels like wood. People usually notice the difference right around the moment someone asks to hold it. See how the Case are made in the Nordics →

Surface Fully charcoal-black thanks to Lastu’s own coloring process. The grain remains visible under the black – in the light it appears, in dim light it disappears. Every black wooden protective case is one of a kind.
Finish Light, non-toxic, water- and dirt-repellent finish. The wood feel stays – not slippery, not cold, not the fingerprint magnet black Case usually are.
MagSafe Available on the product page for several phone models. Does MagSafe need a case?
Engraving Engraving reveals the light shade of birch beneath the black – like scratching away ash. A name, logo, coordinates or symbol stands out in bright contrast.
Durability What do wooden phone cases go through? Read the tests and everyday experiences.

MagSafe – optional, but addictive

MagSafe compatibility can be selected directly on the product page. The magnetic ring aligns the charger and add-ons firmly – “click” and off you go. Perfect for everyday use, the car, your desk and MagSafe accessories.

Screen protector · LEKA

Black birch protects the back. LEKA protects the glass.

HIILI carries the darkness of a charred forest on the back of your phone – but the screen is the surface you look at thousands of times a day. Finish the protection with a LEKA screen protector: a laser-cut protective film that feels like glass but lasts better than traditional tempered glass.

  • +Precision-fit screen protector – a laser-cut protective film made exactly for your phone model (iPhone, Samsung, OnePlus, Pixel). Not a ready-made shelf product, but made to order for you.
  • +Nano PET, not tempered glass – flexes and does not crack during installation like tempered glass. No scratches, no yellowing, full touch accuracy.
  • +2 pcs / €14.90 – two screen protection films for the price of one tempered glass protector. Keep the second as a spare.

What our customers say

Customer Reviews

Overall rating: 4.8 / 5 from 879 reviews.

Kuori istuu hyvin puhelimeen, on napakka ja jämäkän tuntuinen. Magsafe ominaisuus huippuhyvä. Valikoimaan kun vielä saisi takaisin magsafe "tatin" niin kaikki olisi mahtavasti, nyt käytössä vanha "tatti", joka aikanaan ostettu edellisten kuorien kanssa (~4 vuotta sitten). Valmistus/toimitus oli hieman hidasta.

KAAMOS – Puhelimen kuoret aidosta koivusta

Tilaamani kuoret on sellaiset kuin ajattelinkin tilatessani, hienosti puunsävyt ja itse puinen pinta korostuu laitetta käytettäessä puhumattakaan tilaamastani logosta, joka myös onnistui. 5/5

HIILI – Puhelimen kuoret mustasta koivusta 🇫🇮

Customer photo review of HIILI – Puhelimen kuoret mustasta koivusta 🇫🇮

Toimitusaika melko pitkä. Tilauksesta kului 27 päivää kunnes tuote saapui. Kaiverretun logon kohdalla on jotain musteen tapaista joka ei irtoa puhdistamalla. Myöskin Leka näytönsuoja on iphone 15 pro puhelimeen väärän kokoinen. Reunat jäävät ns tyhjänpäälle ja puhelimen sivuista kevyellä puristuksella suoja nousee osittain irti näytöstä ja ilmakuplia ilmestyy kalvon ja näytön väliin. Muuten tuote erittäin hieno ja aion jatkossakin tilata kaupasta suojakuoria.

Elia P. 3/5 Verified

HIILI – Puhelimen kuoret mustasta koivusta 🇫🇮

Toimii ja on kaunis. Se juttu siellä takana se rengas on aivan super. Ainut huono oli se näytön suoja. Se oli suora ja puhelimeni reunat ovat kaarevat eli ei toimineet. Muuten olen aivan super tyytyväinen ja kun seuraavan kerran haluan uudet kuoret tilaan ne teiltä. 😘

Päivi K. 5/5 Verified

HORSMA – Puhelimen kuoret aidosta koivusta

Ei saa mistään parempia ja tyylikkäämpiä suojakuoria. Ei löydy mitään moitittavaa. Todella laadukkaita. Istuu puhelimeen täydellisesti. Oisko jo kolmannet mitkä ostanut eri puhelimiin, muualta en enää osta.

Customer photo review of KAAMOS – Puhelimen kuoret aidosta koivusta

Hyvin istuvat kuoret jotka ovat käyttäjän mieleen, toimitusaika vaan tahtoi olla hieman liian pitkä, 3 viikkoa tilauksesta. Ymmärrän täysin, että yksilöllisesti valmistaminen ottaa aikaa, mutta aiemmin tilantessa ei kyllä ollut näin pitkä viive.

KAAMOS – Puhelimen kuoret aidosta koivusta

Kun Lastu-kuoret saapuivat kotelossaan ja sen avasi, tuoksui terwa! Hieno elämys, ja kertoi siitä, että nyt ollaan aitojen asioiden ääressä. Sukujuuriin liittyy tervanpoltto,siksikin halusin kuoret juuuri teiltä. Kuoret ovat just sellaiset kuin ajattelinkin, personoitu kuvio passasi hyvin valmiiseen tuotteeseen. Toimitus kesti pidempään mitä luvattiin, mutta se vain vahvistaa "käsityöläisleimaa". Kiva ostaa kotimaiselta. Tehkääpä vielä video puun matkasta metsästä kuoreksi, olisi kiinnostavaa seurata koko ketju terwauksineen kaikkineen. Kiitos ja terveisiä tyytyväiseltä käyttäjältä.

TERWA – Puhelimen kuoret tervatusta koivusta

Customer photo review of TERWA – Puhelimen kuoret tervatusta koivusta

Kuori on tyylikäs ja kädelle mukavantuntuinen. Tervan tuoksu oli alkuun voimakas, ehkä turhankin voimakas, mutta se on maltillistunut viikossa eli sen suhteen ei ongelmaa. Puisen takapaneelin istuvuudessa yläreunassa on millin verran heittoa ja sen myötä syntyneeseen rakoon kertyy likaa.

Mikko H. 4/5 Verified

TERWA – Puhelimen kuoret tervatusta koivusta

Kuori vaikuttaa laadukkaalta ja kaiverruksen lisääminen on hieno idea! Olen hehkuttanut kuorta jo muille. Olisin hommannut tällaisen jo aiemmin. Jos vain olisin ollut ko. tuotteesta tietoinen.
