The Tupperware Blue Vent 'N Serve 7 Piece Set is a practical and versatile storage container set perfect for organizing your kitchen. Made from durable plastic, these containers feature airtight seals and air vents to keep your food fresh for longer periods. With a stackable design and easy clean features, these containers are freezer, dishwasher and microwave safe, making them convenient for everyday use. The set includes 7 pieces with various sizes and compartments, including lids, making it suitable for storing a range of items in your kitchen. The blue color adds a pop of fun to your storage solution. I used this vent 'n serve set for about a year and these have only ever been hand-washed, as I do not have a dishwasher. I have way too many of these Tupperware sets and thought I should re-home them. They are a wonderful addition to your collection and are a great product. We will combine shipping on the purchase of more than one item from our store. Shipping is next business day. Thank you for looking.
