Insulated Glass Tumbler with Straw & Lid - Heat-Resistant Borosilicate Cup for Hot & Cold Drinks - Portable Coffee Mug for Commute, Office, | Thomler

Sip Smarter With Shatter-Resistant Glass

This insulated glass tumbler brings durability and style to your daily routine. Built from heat-resistant borosilicate glass, it handles temperature swings without cracking, keeping your morning brew warm and your iced drinks chilled. A snug-fit lid and reusable silicone straw lock in freshness while you move through your day—whether you're rushing to work, settling into your desk, or heading outdoors. The textured exterior offers a secure hold, and the clear walls let you admire every layer of your latte, green juice, or iced tea. Compact enough for any cup holder yet generous enough for a full serving, this vessel replaces disposable cups with a cleaner, more intentional choice.

Why You Need This

• Temperature Control: Borosilicate construction maintains your drink's ideal warmth or chill far longer than standard glass.
• Spill-Proof Transport: Secure lid prevents leaks in bags, backpacks, and car consoles during every trip.

• Shock Resistance: Engineered to survive everyday bumps, drops, and thermal stress without shattering.
