Create your own black wooden phone cases – MagSafe and engraving

Charcoal Birch is like a cold Nordic midnight – black, silent, and beautifully rugged. In Lastu’s own production, the birch surface is treated to be completely carbon black so that the natural wood grain remains visible, like a charred old pine stump in the middle of a frosty landscape.

The surface is finished with a lightweight, non-toxic, and water-repellent lacquer layer that protects against dirt and moisture. The feel is authentic – no plastic, no slippery surface – just warm Nordic wood that travels with you through everyday life like a piece of wilderness peace. Create your own black wooden phone cases – MagSafe and engraving.

Hiilikoivu is a genuine phone case made from Nordic birch — not a printed pattern or a wood imitation. The surface is finished in Lastu’s own process to a deep coal-black while leaving the birch’s natural grain visible. The result is matte-black, subtle and unmistakably wood — not plastic or slippery.
2.Does Hiilikoivu repel water and dirt — can it stand up to everyday moisture and stains? The charred birch surface is finished with a thin, non-toxic, water-repellent lacquer. It...
The charred birch surface is finished with a thin, non-toxic, water-repellent lacquer. It helps repel everyday moisture and dirt—fingerprints and small splashes included. This isn’t a rubbery protective coating; it’s a finish that preserves the wood’s natural feel and makes daily use worry‑free.
3.Can I choose MagSafe compatibility, and will it work with MagSafe accessories? Yes — Hiilikoivu can be made MagSafe-compatible by selecting the MagSafe option on the pr...
Yes — Hiilikoivu can be made MagSafe-compatible by selecting the MagSafe option on the product page. After that you can use MagSafe accessories and chargers, like the KRIP 2.0 MagSafe ring grip and the KARB MagSafe wallet (holds up to 4 cards). You’ll see the effect instantly in the live preview, so it’s right the first time.
4.How will the laser engraving look on your finished Hiilikoivu phone case, and why does it appear black in the preview? Laser engraving is done directly on the birch surface. In the live preview the engraving ...
Laser engraving is done directly on the birch surface. In the live preview the engraving often appears black so it stands out on screen, but on the finished product the engraving always shows the birch’s natural tone - the wood’s warm yellow against the darker surface. Make it yours: add a name, message, symbol or your logo.
