The 5oz my-my™ trainer cups are the ideal transition for when your toddler is ready to move away from a sippy cup. Like all products from Pura, they are 100% plastic-free so you can be sure you are getting the safest, BPA-free and toxin-free cup on the market. Crafted from sturdy 100% silicone, each trainer cup comes with internal volume markings which make measuring your child’s milk or other beverage quick and easy. Each ounce is marked and can be seen inside the cup. This repurpose-able cup is also perfect as a small bowl when feeding baby their first foods or as a snack container for any family member.
