✅ BETTER DESIGN = HAPPY KIDS: A vacuum insulated seal keeps liquids hot or cold for hours, all without sweating or leaving surface marks. Drinking from the straw and the spout is easier, because our unique vents allow air into the cup as you drink. Includes two 9oz cups (260ml) with matching silicone straws.   

✅ TRIPLE-WALL TECH = DISHWASHER SAFE: The entire cup is dishwasher safe, saving you valuable time! The cup and straw can be placed anywhere in the dishwasher and the lid is top rack safe. PopYum's premium 18/8 stainless steel contruction features Triple-Wall technology which makes the cups dishwasher safe and encapsulates the delicate vacuum solder seal. The durable TOUGHcoat finish won't chip or peel.   

✅ TWIST-LOCK LID = LESS MESS: The Twist-Lock lid reduces spills since the lid won't pop off when the cup is dropped. While drinking from the lid, the Flip-N-Lock lid closure stays out of the way by locking open. When the lid and the straw opening are closed the cup won't leak.   

✅ STRAW STOPPER + STACKABLE: A straw stopper-ring keeps the 100% silicone straw in the cup, even if your little one pulls on it. We also designed the cups to be stackable with or without their lids.   

✅ SAFE MATERIALS: PopYum only sources ultra-premium and tested safe materials. PopYum is BPA, BPS, latex, lead, nitrosamines, PET, phthalates, PVC and TPE free.
