Re-Play bowls, plates, cups, utensils and snack stacks are made from USA FDA-approved BPA-free recycled plastic milk containers and polypropylene. Natural coloured containers from food-related applications (usually milk and other drink containers) are recycled through a unique process that the USA FDA has approved for food contact. The plastic is specially selected and cleaned to meet strict purity standards. Each finished product line, in each colour, is then third-party tested, assuring buyers that the Re-Play final product meets fully the FDA requirements for contact with food. The colour concentrate is safe for food contact; all the ingredients in the colours are FDA approved. Re-Play is top rack dishwasher safe and should not be used in the microwave.
