【PRACTICAL, HOLD 2 DRINKS 】This tumbler seamlessly transforms into a 30oz upper part and a 10oz bottom part. It is perfect for keeping your coffee hot and your water cold at the same time.

【NOT JUST A TUMBLER FOR DRINKS】You can put some cookies or mini candies in the bottom cup for a quick energy boost and use the upper cup for your beverage. This stainless steel insulated tumbler will keep everything nice.

【CUP HOLDER FRIENDLY】The car thermal mug has a narrow base design, making it fit nearly any car cup holder. When you use this spill-proof tumbler with straw, you can say goodbye to spills and tilting during drives. It fits into your car cup holder only when the bottom part is screwed on.

【2 DAYS ICED, 12 HRS COLD, 6 HRS HOT】The detachable insulated tumblers adopt double-walled vacuum insulation that can keep your beverage hot or cold for hours.

【LEAKPROOF LID】Crafted from non-toxic, 100% BPA-free, 18/8 stainless steel, our tumbler guarantees safety and durability. Package includes: a 40 oz detachable insulated tumbler, a reusable straw, and a leakproof lid.

【DISHWASHER SAFE】Bid farewell to the hassle of hard-to-reach corners. The water cup with a straw and lid is easily disassembled, and you can toss it in the dishwasher for quick and hassle-free cleaning. HAND WASH ONLY FOR LID.
