Rubbeeblocks were created to provide an alternative to plastic or wooden blocks that find their way to your baby’s mouth. Made from all natural rubber (hevea brasillensi), rubber blocks are a safe, early stage building set that includes 8 thoughtfully designed pieces. These blocks are safe and fun at any age, on dry land or in the bath! BPA-Free, Paraben-Free, Phthalate-Free. No masking agents or chemicals softeners. Please Note: This product is made from 100% natural rubber from the Hevea Tree. Various conditions including humidity, temperature, season of harvest, etc. can effect the color (making product appear darker or lighter), and smell (scent of natural rubber). The beauty of 100% natural products is that their variability is a confirmation of nature itself--the tree in spring is much different than the tree in autumn.
