Product Use & Care

Q1: How long can it keep drinks hot or cold?

Our double-wall stainless steel vacuum insulation keeps drinks hot or cold for 4–6 hours.

For the best performance, preheat or pre-cool your tumbler with hot or cold water before filling.

Q2: Is the lid leak-proof?

The lid is designed for secure everyday use — it seals tightly and won’t leak under normal carrying conditions.

However, we recommend keeping it upright when inside a bag.

Q3: Can I wash the tumbler in a dishwasher?

We suggest hand washing with warm water and mild soap to maintain the soft matte finish and the integrity of the lid seal.

Q4: How long does shipping take?

Most orders are processed within 2–3 business days and delivered in 7–15 business days, depending on your region.

More details can be found in our Shipping Policy.
