RIWI® FAQ – Frequently Asked Questions

Very safe – and that’s especially important to us. Our blocks are made of a special foam developed specifically for children's toys. They’re tested to European EN71 standards, the US ASTM F963 standard, and OEKO-TEX Standard 100 – all certified by the independent testing institute TÜV Austria. Plus, every block is made in the EU – for trusted, certified quality.

Cleaning is easy – either in the washing machine or by hand. Please don’t use fabric softener and opt for a child-friendly detergent. This way, the blocks stay beautiful and safe for a long time.
