Meet Rio, the very first insulated tumbler with a telescopic straw. The colorful 950 ml (32 oz) leak-proof tumbler keeps your smoothies, milkshakes, or other drinks cool for up to 24 hours. Rio is made of double-wall vacuum-insulated 18/8 stainless steel for the best quality. Plus, it is BPA-free, so you can drink safely and healthily. Place your Rio in the dishwasher for easy cleaning.
