Even though the design was originally developed for kids, it works great for grown-ups, too. Toss a SipSnap on a Mason jar or glass and your drink will stay contained.

These lids are great for families out at restaurants, too—no need to bring along a sippy cup. Use SipSnaps to turn the restaurant’s glass into one.

Made of high-quality, food-grade silicone that is BPA– and phthalate-free, SipSnaps are dishwasher safe. Plus, you can pop them into boiling water to sterilize and, when you’re done, fold and stack them together for easy storage. They even have a handy case for when you’re out and about.

With SipSnap, it’s easy to stop spills. Just put a lid on it.
