Design and protection
+ Textured edge profile – birch gives the back a natural grip. Wooden phone cases stay secure in your hand and won’t slip.
+ Raised edge protects the screen – place your phone on the table without the screen touching. Drop protection tested →
+ Raised camera frame – the lens doesn’t touch the table, so no scratches.
+ Slim and light. Birch is naturally lighter than most fully plastic protective phone cases — you won’t feel it in your pocket, but you will in your hand.
+ MagSafe compatibility available — wireless charging and magnetic accessories at full power. MagSafe and your own logo →
+ Engraving or your own image — name, date, symbol or logo as a contrast on light birch. Engraving options →
