• TESTED FOR SAFETY BY A 3RD-PARTY: We don't mess around when it comes to our children so all insulated sippy cups for toddlers are rigorously tested by certified US laboratories
• SUPER EASY TO CLEAN: Lids and straws are top rack dishwasher safe. Hand washing your metal kids sippy cups are recommended to maintain your vibrant coral and yellow stainless steel tumbler colors
• NO CHIPPING OR PEELING: Each unbreakable toddler smoothie cup is powder-coated so it will resist chipping, peeling or melting better than any painted stainless steel baby training cup
• FOOD GRADE MATERIALS: Food-grade silicone and 18/8 stainless steel are used in these baby cups. For these straw cups for toddlers 2 years old is the minimum recommended age - Training cups for babies
• ABOUT CUPKIN: Our goal is to produce better-looking and more practical stainless steel tumblers for our children, and yours! Designed in Seattle, WA, and built to last, our double walled powder coated cups will soon become a family staple.
