Certifications & Quality Assurance

We prioritize precision, durability, and aesthetic integrity, with every tumbler undergoing rigorous testing to meet global standards:

● Food Safety Certifications: FDA (U.S.) and LFGB (EU) compliance for borosilicate glass, ensuring no harmful chemicals leach into beverages.

● Material Testing: Borosilicate glass is certified for thermal shock resistance (surviving 110°C temperature changes) and impact resistance (passing 12+ drop tests from 1m height).

● Factory Standards: Our production facility is ISO 9001 certified, with strict quality control from glass cutting to laser engraving.

● Quality Control Process:

1. Wall Uniformity Test: Each tumbler is measured to ensure 3mm wall thickness for balanced weight and grip.

2. Laser Engraving Adhesion Test: Engraved logos are subjected to 100+ dishwasher cycles to verify scratch resistance.

3. Stack Load Test: Tumblers are stacked with 8kg of weight to confirm stackable base durability.

4. Final Audit: A 5% sample of each batch is inspected for clarity, angular precision, and engraving alignment.

Customization & Production Process

We offer precision customization tailored to modern brand aesthetics, with a focus on subtle, high-quality branding:

● Custom Options:
