The keycaps are made of Elegoo resin. The resin is being cured by UV light. If the resin is fully cured the resin is not toxic to your health. We are doing our best to fully cure the keycaps before shipping away. Every keycap will be checked for uncured spots. The warnings are in German. We will translate them for you.

- Keep in temperature of 20 to 25 degrees celcius. 

- Avoid direct contact with the uncured resin.

- Keep away from children.

- If the resin gets in contact with skin, wash your skin with water.
