⚖️ Seller Warranty & Marketplace Dispute Conciliation

Contact support under the seller's warranty and marketplace return policy if, after following all usage and troubleshooting instructions, the tumbler exhibits manufacturing defects such as persistent leaks from the body (not the lid), dents that compromise usability, or if its temperature retention capability is demonstrably null and not related to misuse or natural wear. Such situations may indicate a manufacturing defect.
