TERWA – Phone case made from tarred birch
+ Lisää MagSafe ja personointi
TERWA phone cases are made from Nordic birch, treated with traditional tar – the surface darkens and seals up, making it naturally resistant to water and dirt. The finish isn’t sticky or staining; it just feels like real wood. Because it is. Engrave your own text, logo, dog.. anything, and admire the live preview. Carry something with roots.

TERWA – wooden tar birch phone cases & covers
iPhone, Samsung, OnePlus, Pixel, Nothing – dark brown, engravable
The campfire has smouldered overnight. Mist rises from the lake, the coffee pot starts to hiss, and the air carries that smoky, resinous scent you won’t find in the fragrance aisle. TERWA is a handmade wooden phone case made from tar birch – dark brown and genuine, and it smells exactly like that morning. You pick up your phone about 56 times a day; here’s a case that gives those moments something extra. The wood grain lives on the surface like growth rings in a stump, and no two are alike. Fits iPhone 17, 16, 15, 14, 13, Samsung Galaxy, OnePlus, Google Pixel, and Nothing models. Add MagSafe or engrave a name and create your own TERWA case.
In the wilderness of Kainuu, tar pits smoked for weeks, tar boats came down the river to Oulu, and the whole city smelled of it. The same substance held sailing ship ropes together across the Atlantic. Lastu was born in that city. TERWA is that tradition in a modern form: a phone case treated with the same stuff – just on a slightly smaller scale.
Material: tar birch – smoke and grain
- Tar birch – dark brown like a coffee pot left by the campfire, with the grain showing through. Every wooden phone case is one of a kind.
- The tar treatment repels water splashes — no stickiness and no staining your hands. Morning dew, a rain shower, and fishy hands are fine. Swimming is not.
- A subtle, genuine tar scent — not perfume. Strongest during the first few weeks — then it takes you to the smoky sauna bench and a September lakeside rock — before becoming something only you notice.
