Stanley Cup Accessory Set with Silicone Stoppers, Straw Covers, and Protective Boot

This accessory set is designed specifically for users of 30oz and 40oz tumbler models. The kit includes six silicone spill-proof stoppers, two straw cover caps compatible with 9-10 mm straws, and one protective silicone boot. These components are intended to prevent accidental spills while traveling, keep the drinking straw hygienic when not in use, and provide a cushioned base for the cup to prevent surface scratches or loud noises when placed down. Buyers should evaluate the specific diameter of their existing straws to ensure compatibility with the 9-10 mm cap size before purchasing. Because these items are silicone accessories, they may suit users looking to customize their hydration setup without modifying the original vessel.
