Silicone Leak Stoppers and Straw Covers for 40oz and 30oz Tumblers
This accessory set provides silicone leak stoppers and straw covers designed to secure large tumblers.
This product is a specialized accessory kit consisting of six pieces designed to provide extra security for large insulated tumblers, specifically those in the 30oz and 40oz size range. The set includes two straw covers, two square spill stoppers, and two round leak stoppers. Made from silicone materials, these components are intended to prevent accidental spills or leaks while the tumbler is being transported or used in different environments. When evaluating this purchase, a buyer should consider whether their specific cup model matches the dimensions of the square and round stoppers provided. Because this set does not include the actual tumbler, it is strictly an add-on for existing equipment. Buyers may want to compare the material thickness and the specific fitment types against other silicone seals to ensure they provide sufficient protection for their preferred beverage container.
