Made using European-sourced FSC-certified wood. Grimm's colours are non-toxic, water-based stains that are absolutely harmless and tested in-depth for colour fastness in contact with saliva. This test uses a liquid comparable to standard human saliva. However, some people’s saliva do vary from the “standard”, so some colour may transfer under those conditions, but the stains are harmless.

DAMAGES & CARE OF WOOD: If you clean Grimms wood products only use a damp cloth. Do NOT submerge in water. Do NOT use hot water or disinfectant. Grimms stands for quality and long life. When making our toys, we carefully select the wood without defects. At each step, the quality of the wood is checked. But wood lives and responds to air changes. Wood is a natural product and not indestructible. Children should be advised and prompted to use caution with their special toys. If something breaks, repair the damage with wood glue.
