Absolutely! We only use safe, water-based finish on our beech wood blocks. All of our products go through stringent lab testing to ensure that we are not only compliant to Toy Safety Standards, but that we exceed those standards including: US (ASTM-F963), Canada (SOR 2011-7 & SOR 2018), Australia & New Zealand (ISO 8124), the EU & UK (BS EN-71), and Japan (JFSL). We are proud to offer a wood toy that is not only safe for your kids, but for the environment.
