Premium 550ml Heat-Resistant Glass Bottle with Bamboo Lid & Silicone Cover

Crafted from ultra-durable borosilicate glass for superior thermal shock resistance (withstands -20°C to 120°C). Hand-fitted bamboo lid features precision CNC machining for airtight sealing, paired with food-grade silicone sleeve for non-slip grip.

Innovative 3-layer leakproof design: threaded bamboo collar, tapered silicone gasket, and reinforced glass neck. Ideal for specialty coffee shops, yoga studios, or outdoor adventures—preserves beverage temperature for 3+ hours.

Wholesale-ready minimalist packaging (stackable design reduces shipping costs by 15%). Laboratory-tested for BPA-free safety and dishwasher durability (500+ cycles). Compatible with most car cup holders and backpack pockets.

Note: Bamboo grain variations occur naturally—each piece is uniquely textured. Bulk orders receive custom branding options on silicone sleeves.
