TERWA – Phone Case Made from Tarred Birch 🇫🇮

2025-08-27T13:11:29+03:00

On average, you pick up your phone 56 times a day.

COULD IT FEEL MORE REAL?

TERWA is made from Nordic tar birch — wood infused with tar in the surface treatment. A deep blue-brown tone and a subtle scent: wet moss, a distant campfire, the silence of the wilderness. No mass production, no two exactly alike. MagSafe available.

01

Wooden phone cases made from tar birch. No copy.

Every wooden phone case is made from genuine Nordic birch. Tar adds depth — the grain stays visible, and every case is unique.

02

Oulu. Tar tradition.

Lastu was born in Oulu — the historic tar city. TERWA continues that tradition in a modern form. Tar-treated birch in your pocket, every day.

Not from stock.
From the Nordic countries, made to order.

Every TERWA case is made to order from Nordic birch. The tar-treated surface repels water splashes, doesn’t get sticky, and won’t stain your hands. When you pick up your phone, you feel warm wood — not cold plastic.

Tar A subtle natural scent — wet moss, a distant campfire. No stickiness, no staining.
