Freshness and safety go hand in hand. If contents are not kept at the correct temperature, potentially pathogenic bacteria can form quickly and cause food and beverages to spoil. All stainless steel products feature a stainless steel Thermos straw, making it easy to keep drinks cold when on the go. This bottle, with a capacity of 10 Oz, will keep its contents cold for up to 12 hours. This contoured bottle can be easily grasped and held by small children's hands. Thanks to its durable double-walled stainless steel construction and Thermos vacuum insulation, the bottle with straw accumulates no condensation and leaves no water rings. A simple-to-open hygienic push-button lid reveals a comfortable-to-use retractable silicone straw. Cleaning is simple; simply unscrew the lid to completely remove the straw and disassemble it into two pieces for easy cleaning. The bottle and straw components can go in the top rack of the dishwasher; however, hand washing is recommended for best results. Do not use with hot liquids.
