Lastu protective cases are made from FSC-certified northern wood species (curly birch, ash / dead pine, oak, walnut), genuine reindeer and salmon leather, and shock-absorbing TPU frame. Each wooden phone case is unique, as the grain pattern naturally varies.
The case's TPU inner frame and 1.5 mm raised edge protect the screen and camera.
The model has been SGS laboratory tested to MIL-STD-810H 516.8 – 2 meter drop test (26 angles), so your phone reliably withstands everyday bumps.

The total thickness of the case is about 1.3 mm and the weight is on average 28g, so the lightweight wooden protective case does not make the device bulky nor does it prevent wireless charging.

Wipe the surface with a dry microfiber cloth and, if necessary, add a drop of natural oil along the grain of the wood. It is advisable to protect the leather with a colorless conditioner. Avoid strong chemicals so that the domestic wooden case develops a beautiful patina and lasts for years.
