Certifications & Quality Assurance

We prioritize safety, sustainability, and aesthetic longevity, with every tumbler undergoing rigorous testing to meet global standards:

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

● Eco-Certifications: FSC (Forest Stewardship Council) certification for bamboo lids, confirming responsible sourcing and renewable material use.

● Material Testing: Borosilicate glass is certified for thermal shock resistance (surviving 100°C temperature changes) and impact resistance (passing 15+ drop tests from 1m height).

● Factory Standards: Our production facility is ISO 9001 certified, with strict quality control from raw material sourcing to final glaze/print application.

● Quality Control Process:

1. Temperature Shock Test: Each tumbler is filled with boiling water and immediately submerged in ice water to confirm crack resistance.

2. Print/Glaze Adhesion Test: UV prints and gradient glazes are subjected to 50+ dishwasher cycles to verify scratch and fade resistance.

3. Lid Seal Test: Bamboo lids are pressure-tested to ensure 100% leak-proof performance when inverted.

4. Final Audit: A 5% sample of each batch is inspected for glass clarity, print alignment, and gradient color consistency.
