STANLEY Set of 2 Protective Covers and Straw Caps for Thermo Mugs 0.89L/0.59L The Quencher Boot + Straw Topper Light Gray

Give your Stanley Quencher tumblers the protection they deserve with this dedicated accessory set. Unlike universal silicone sleeves that slip and stretch, these boots are precision-molded to fit both 0.89L (30oz) and 0.59L (20oz) Quencher FlowState tumblers, hugging the base securely while adding a soft-touch grip. The included straw caps snap over your straw to keep dust and spills at bay, making every sip cleaner and more hygienic. Crafted from food-grade silicone, the set is BPA-free, odorless, and dishwasher safe, ready for daily use.

In daily use

Slide the boot onto the base of your tumbler and feel the difference — no more clanking on desks or sliding on smooth surfaces. The silicone absorbs minor impacts and prevents scratches on both the tumbler and your furniture. When you're on the move, the straw cap keeps your drinking straw clean from dirt, lint, and accidental spills. Both accessories are reusable and simple to remove for cleaning, so your tumbler stays in top condition day after day.
