Every Gonomax tumbler comes with a 1 year warranty from the date of delivery. It covers problems caused by how the tumbler was made or printed, not wear from everyday use or accidents.
What is covered
- Printing that peels, flakes or fades unevenly under normal use and the care steps below
- A lid that doesn’t fit the tumbler or a seal that is missing or misshapen out of the box
- Seams, welds or the stainless steel body showing a manufacturing flaw
- Parts that were missing from the original package
What is not covered
- Dents, scratches or chips from drops and knocks
- Damage from a microwave, oven, open flame or freezer
- Print wear caused by harsh cleaners, scouring pads or the dishwasher
- Normal signs of use, such as small marks on the base
- Spelling mistakes in the name entered at checkout
- Tumblers changed or repaired by someone other than us
Damage that is visible when the parcel arrives should be reported within 7 days of delivery under our Return and Refund Policy.
Making a claim
- Email support@gonomax.com with your order number.
- Describe the problem and attach clear photos of the tumbler and the affected area.
- We review the claim and reply by email. If it is covered, we send a replacement tumbler, or refund the item if a replacement isn’t available.
We may ask you to send the tumbler back for inspection; if so, we will explain how.
Care tips that keep the warranty valid
- Wash by hand with warm water, mild soap and a soft sponge.
- Keep the tumbler out of the microwave; stainless steel is not microwave safe.
- Take the lid apart and dry all parts before putting it back together.
