Stanley cup owners, this accessory kit is exactly what you need to upgrade and protect your favorite tumbler! The set includes everything - two square spill stoppers, two round lid leak stoppers, two decorative straw covers (cactus and tropical fish designs), and one silicone boot that fits perfectly on the bottom of your Stanley. The 360-degree anti-leak design on the spill stoppers means no more worrying about accidental spills in your car, bag, or home. The silicone boot is brilliant - it protects your cup from scratches, dents, and reduces noise when you set it down, while the non-slip base prevents tipping. The straw covers keep dust out and provide splash protection, and they fit standard 9-10mm straws perfectly. Made from food-grade silicone that's odorless, durable, and dishwasher safe for easy cleaning. Everything is specifically designed for Stanley Adventure Quencher 40oz H2.0, IceFlow 20oz/30oz, and similar tumblers with bottom diameters between 2.75-2.96 inches. Whether you're commuting, camping, hiking, or just using your Stanley around the house, these accessories make your cup more functional, protected, and personalized. It's one of those kits that makes you love your Stanley even more while solving those little annoyances like spills and scratches.
