Our Refund & Exchange Policy applies to all purchases made online at mammothmug.com. If you have purchased your mug from a retail location, please note that you must adhere to the store's return policy, as we do not handle any retail location purchases. 

It is important to note that Mammoth Mug does not cover damage caused by normal wear and tear, accidental dropping, improper care or cleaning, non-standard usage, or negligence. Our product is designed for water carry and consumption, and it is not intended to withstand large drops, force, impact, or exposure to extreme conditions.

We value our customers and strive to provide the best service possible. If you have any questions or concerns regarding our Refund & Exchange Policy, please do not hesitate to reach out to our customer support team at sales@mammothmug.com. We are here to assist you and ensure that you have a positive experience with our products.

Thank you for choosing Mammoth Mug. We appreciate your support and look forward to serving you in the future.

We go on a case-to-case warranty on our Mammoth Mugs. If there are any issues with your Mammoth Mug, please email the customer support team (sales@mammothmug.com) the problem and provide us photos. Based on the photos we will determine if the impact falls under a manufacturing issue or if it was the impact itself that led to the problem.

Due to the medical-grade plastic, Mammoth Mugs are NOT dishwasher safe. "Hand wash only" is indicated at the bottom of your Mammoth Mug, as well as under each product description. Mammoth Mugs are not made to withstand high heat for long periods of time. Please keep out of direct sunlight and wash with warm water.

We do not guarantee replacements or reimbursement for any accidental and/or usage damage to your Mammoth Mug.
