Do you need help?

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 tested in an SGS laboratory with the MIL-STD-810H 516.8 – 2 meter drop test (26 angles), so your phone will reliably withstand everyday bumps. Read more about protection.

Yes. The optional internal neodymium ring makes the case fully MagSafe-compatible with iPhone, Samsung, Pixel, and OnePlus models, allowing wireless charging and accessories to attach just as securely as with Apple’s original case. Add MagSafe functionality to your case on the product page.

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 prevent wireless charging. Read more.

Yes. Unused products have a 14-day right of return. Personalized engravings are unique and do not have a right of return, but they can be exchanged for a new one at 50% of the price within six months.

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.
