Bioserie's founders have had their own experience of looking for the right toys for their own babies. They’ve noticed that it’s not easy to find baby toys that are all together free of potentially harmful chemicals, really fun to play with, easy to clean, and sustainable. They are doing their best to bring to life the ideal essentials that will support other babies' early discoveries. Bioserie toys are made from a special blend of modified PLA (Polylactic Acid) and natural additives. They contain 0% oil-based chemicals, because their raw materials are derived from plants, not oil. They are the first ever products in their category to have received USDA’s BioPreferred Program 100% biobased certification. Several years of research and development on bioplastic injection molding technology allows for the best possible product quality and finish. Since 2015, Bioserie toys have won several toy and consumer awards in the USA and in Europe in the green category.
