There are four pieces in the set: a plate, a bowl, a tumbler, and a water bottle. All the dishes are covered in colorful artwork, sturdy and perfectly sized for small hands. The water bottle has a capacity of 16 ounces and is easy to take on the go, with a built-in carrying loop and a pop-up cover that keeps the spout clean. Everything is made of durable plastic, which is completely BPA free and dishwasher safe. Do not microwave.
