This is a modern and eco-friendly glass tumbler designed for stylish, sustainable drinking. The tumbler is made of clear borosilicate glass, which is known for being lightweight yet durable. It comes with a natural bamboo lid that includes a snug silicone ring to prevent leaks. The standout feature is the reusable glass straw, which fits neatly through the lid. The straw is bent at the top for easy sipping and extends inside the tumbler at an angle to reach the bottom. Ideal for cold drinks like iced coffee, smoothies, or juices, this tumbler is both functional and environmentally conscious.
