Perfect Compatibility: This water bottle adapter is designed for Cirkul Flavor Cartridge and is only compatible with Stanley IceFlow 20 & 30oz. Please confirm your water tumbler model before placing an order. New Upgrade: Unlike other adapters, our tumbler adapters do not require extra flavor cartridge lids. It is an upgraded version with an integrated structure, and the top can be directly connected to Cirkul flavored cartridge. Reduce an annoying step and make drinking water easier! No Water Leakage: YOUSHARES water bottle accessories are compact and precise. After repeated numerous tests, it was ensured that, like the original cup lid, it effectively maintains the temperature in the cup without leaking a drop of water. Food Grade Material: The water bottle transfer adapter is made of BPA-free plastic and food-grade silicone, which is reusable and will not deform, ensuring that every sip of water you drink is clean and safe. Easy to Use: Dishwasher-safe and odor-free. When using, just connect it to Stanley IceFlow 20/30oz water cup, insert the flavor cartridge, and enjoy the ultimate hydration. It is lightweight and portable, perfect for hydrating anytime, anywhere, whether you are doing outdoor sports, going to work, or traveling.
