350ml double wall mug with handle

The Featherlight Revolution: CrystalClarity Double-Wall Tumbler​

Discover glassware redefined through advanced materials science. Weighing a mere 180g – lighter than most smartphones – our high-borosilicate tumbler achieves the impossible: combining ethereal lightness with laboratory-grade durability. The elegant conical silhouette (top diameter 3.93"/10cm, height 6"/15.3cm) features a gracefully arched handle designed for natural ergonomics, making this your most intuitive drinking companion.

​Thermal Intelligence Engineered​
Experience the double-wall advantage that ordinary glasses can't match:
• ​Instant Touch Comfort​ - The 4mm vacuum-sealed air barrier creates a thermal buffer zone, keeping exterior surfaces at ambient temperature whether holding 200°F coffee or ice-cold beverages
• ​Condensation-Free Performance​ - No more watery rings on your wooden tables or documents
• ​Stable Temperature Maintenance​ - Enjoy hotter coffee for 27% longer and colder drinks for 35% longer versus single-wall glasses 

​The Borosilicate Difference​
Unlike cloud-prone sodium-calcium glass that develops permanent mineral haze after 50 washes, our pharmaceutical-grade borosilicate composition:
• Dishwasher safe
• Resists thermal shock up to 150°C differential 
• Preserves taste purity without metallic aftertaste

​Seamless Lifestyle Integration​
Our four-point safety assurance system ensures worry-free usage:

1. ​Zero Heavy Metals​ - Third-party verified lead-free construction
2. ​Endocrine-Safe​ - Certified BPA-free materials
3. ​Cleaning Convenience​ - Top-rack dishwasher resilient
4. ​Temperature Versatile​ - Freezer-to-microwave transition ready (-20°C to 150°C)

​Designed for Real Hands​
The precisely angled handle (visible in your image) creates a balanced 12° tilt when lifted, preventing wrist strain during prolonged use. At just 4.49"/11.4cm base diameter (as shown beside beverage can), it fits standard cup holders while providing generous 450ml capacity.

​Engineered for Lifetime Performance​
We've eliminated all compromise points:
✓ No glued seams - monolithic construction
✓ No plastic taste transfer
✓ No thermal shrinkage stress points
✓ No surface degradation from citrus acids

​The Daily Ritual Redefined​
From morning espresso to evening craft soda, experience beverages as nature intended - visually pristine, perfectly tempered, and effortlessly elegant. The CrystalClarity tumbler isn't just container; it's a sensory enhancement system where advanced materials elevate everyday moments.
