Stop carrying two bottles and optimize your hydration. This premium silicone insert lets you carry two drinks in one tumbler, keeping your coffee hot and your water cold without ever mixing flavors.
Question 1: Will this divider fit my specific 40oz tumbler or Stanley cup?
Answer 1: Yes. It is precision-engineered to fit most standard 40oz high-capacity tumblers. The flexible, premium silicone ensures a snug, secure fit that stays in place even during your most hectic morning commute.
Question 2: Can I actually carry a hot drink and a cold drink at the same time?
Answer 2: Definitely. The high-grade silicone is rated for temperatures from -40°C to 230°C. This thermal resistance allows you to carry steaming coffee and ice-cold water simultaneously in one hand without any flavor or temperature transfer.
Question 3: Is it easy to clean, or will it hold onto old flavors?
Answer 3: It is completely dishwasher-safe and made from non-porous, BPA-free silicone. This means it won't absorb odors or stains, ensuring your water never tastes like your morning protein shake after a quick wash.
