Tired of your glass spray bottles or water bottles slipping, tipping over, or getting dinged up? These silicone sleeve bottoms are a simple and clever fix. You get 8 of them in black – enough to protect all your bottles. They're made of soft, stretchy silicone that fits snugly over the bottom of your bottle. The material grips surfaces well, so your bottles won't slide around easily. Each sleeve is about 2.95 inches in diameter and 1.77 inches tall, and they stretch to fit a range of bottles from 12 oz up to 24 oz – perfect for cosmetic sprayers, essential oil bottles, sports water bottles, or even some mason jars. They cushion against bumps and help prevent breakage if you drop them. Plus, they're washable and reusable. Just slide one on the bottom of your bottle and you're good to go. A small upgrade that makes a big difference in keeping your bottles safe and stable.
