FUNtainer™ Stainless Steel, Insulated Straw Bottle - Charcoal - 16 oz.Constructed with double wall stainless steel, this 16 ounce straw bottle is virtually unbreakable and built to withstand the demands of everyday use. Featuring a hygienic, push-button lid, this straw bottle is easy to open and drink from. Also included on the lid is an integrated, flip-up carrying loop. The FUNtainer Straw Bottle comes equipped with a breakaway lid designed to simply snap off if accidentally dropped while the lid is open. The lid can then be easily snapped back into place, making this a great, worry-free choice for parents and kids alike. In order to maximize the incredible insulation technology, it is recommended to pre-chill the bottle just prior to use. This can be accomplished by filling the bottle with cold tap water, attaching the lid and letting it rest for a few minutes. Before you are ready to use, simply empty the water and fill with your favorite beverage. Attaching the lid will further increase the thermal efficiency.Features:Vacuum insulation technology for maximum temperature retention, not for use with hot liquidsDurable stainless steel interior and exteriorHygienic push button lid with pop-up straw and integrated carry handleKeeps cold 12 hours16 ounce capacity; hand washing recommendedrinks refreshingly cold for up to 12 hoursDurable stainless steel interior and exterior withstand the demands of everyday use; Hand wash recommendedHygienic push button lid with pop-up silicone straw is easy to useFlip-up carrying loopSpecifications:16 ounce capacityMeasures 2.6"W x 2.6"D x 8.6"H
