Re-Play's Straw Cups are ideal for everyday dining. Perfect for backyard parties, picnics, camping, barbecues, etc. You will find yourself using them as the go to on-the-go children's cups! Durable AND affordable, our straw cups are perfect for everyday use - as well as outdoor parties, picnics, and barbecues. Mix and match these colorful cups with our utensils, plates, and bowls, to create a vibrant tableware set! While our products are microwave safe, we only recommend putting them in for short 20 second bursts, in order to warm the food, NOT COOK. Extended time in the microwave can cause uneven heating and hotpots in the food. Do not put Re-Play in a regular oven. Re-Play products are dishwasher safe - because every mom and dad deserve less clean-up time! When serving red sauces, we recommend immediately scrubbing and rinsing, using a grease-cutting, liquid soap before dishwashing. Our family owned and operated company uses SUSTAINABLE, Recycled HDPE (Milk Jugs) in our manufacturing process. Re-Play saves 1 milk jug from the landfill every 6 seconds, completely reducing single use plastic.
