Our designs are applied using a highly durable laser printing process, built to withstand heavy daily use. While no finish is indestructible, your tumbler will maintain its vibrant look for a long time. To ensure the maximum longevity of both the print and the thermal insulation, we recommend hand-washing with a soft sponge.

Our lid is designed to be highly spill- and leak-resistant during daily use, like in a car's cupholder or on your desk. However, we do not consider it 100% leak-proof if turned upside down or tossed loosely in a bag. For transport in backpacks, we recommend keeping it in an upright position.

No. We exclusively use 18/8 food-grade stainless steel, which is the industry standard for high-quality kitchenware. This material is specifically chosen for being non-porous and non-reactive, meaning it preserves the original flavor of your beverage without transferring any metallic taste.

Yes. We take authenticity very seriously. All of our collections featuring characters, logos, or art from well-known franchises are 100% official, licensed products created in partnership with the rights holders. This ensures you are receiving a genuine item that supports the creators you love.

Yes. In addition to the vacuum between the double steel walls, the interior of our tumblers has a copper lining. This extra layer reduces temperature transfer via radiation, acting as another barrier to prevent heat (or cold) from escaping. It's an engineering detail that elevates the insulation performance to a higher level.
