⚖️ Seller Warranty & Marketplace Dispute Conciliation

Contact support under the seller's warranty and marketplace return policy if, after following all usage and maintenance instructions, the tumbler exhibits persistent leaks from the lid (even after cleaning and checking the seal), or if temperature retention is demonstrably ineffective (not maintaining temperature for a reasonable period, even without opening), indicating a potential manufacturing defect in the vacuum insulation.
