Our bamboo toddler dishes are made of natural bamboo fibers, then molded using a binding resin. The resin has a low amount of food-safe, FDA-approved melamine. This allows for the dishes to be washed in the dishwasher. (Despite what other manufacturers claim, there are no dishwasher-safe bamboo products on the market made without this resin.) Our bamboo dishes are BPA free, non-toxic, phthalate-free, PVC free, lead-free, cadmium-free, mercury-free, and all of our products undergo strict quality control testing. They pass LFGB and FDA standards. These standards run tests to see if any dangerous particles leach at different temperatures of liquid they come in contact with over different periods of time. The results show that although there may be some melamine, it does not leach into the contents of whatever comes in contact with it.
