HIILI – black wooden phone cases & phone cases
made from genuine charred birch | iPhone, Samsung, OnePlus, Pixel, Nothing
The campfire has burned out, but the embers still glow. That color is now in your hand. HIILI is a black wooden phone case made from genuine Nordic birch – the black runs into the wood itself, not sprayed on top. No plastic, no printed wood grain, not the same black case every other person already has. The grain pattern lives beneath the darkness, so no two phone cases are alike – we don’t even try. Fits iPhone 17, 16, 15, 14, 13, Samsung Galaxy, OnePlus, Google Pixel, and Nothing models. Choose MagSafe, engrave a name, or add your own image.
Choose your phone model, shade, MagSafe compatibility, and add engraving, your own image, or a logo if you like. The live preview shows your choices before you order. Fits iPhone, Samsung, OnePlus, Google Pixel, and Nothing phones.
This is the wooden phone case for you if you want a black case without the mass-produced feel. Made in the Nordics, to order in Oulu – not pulled from a shelf.
Material: genuine birch, multiple shades
- Hiili – fully charcoal-black birch with the wood grain visible. A unique black wooden phone case.
- Lumi – a light wooden phone case made from natural birch. Clean, calm, and authentic.
- Rosa – warm light pink birch with the wood’s natural structure still visible.
Birch feels different in your hand than plastic: warm, light, a little like the spine of a hardcover book. Every wooden phone case is one of a kind – the grain pattern is the wood’s fingerprint.
Structure and protection
Not from stock. Made to order in the Nordics.
Black birch. Not black plastic.
Every Hiilikoivu phone case is made to order in the Nordics from Nordic birch. Lastu’s own dyeing process carries the black deep into the wood while leaving the grain visible — so the case is black in a different way every time. This is a phone case that looks black but feels like wood. People usually notice the difference right around the moment they ask to hold it. See how the Case are made in Oulu →

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 protective film laser-cut 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 won’t crack during installation like tempered glass. No scratches, no yellowing, full touch accuracy.
- +2 pcs / €14.90 – two screen protector films for the price of one tempered glass protector. Keep the second as a spare.
