Transform any glass or mug into a spill-proof cup. These stretchy, non-toxic silicone lids create a suction seal that keeps beverages neatly contained. And the sippy-style opening works well for kids, too.

  • Materials: Silicone
  • Care: Before first use, wash with warm water and soap and boil in water for 2 minutes to sterilize. Dishwasher safe, top or bottom rack
  • Includes: 2 universal silicone sippy cup lids
  • Instructions: Make sure the lid and cup are dry for a proper grip. Stretch out the lid and align the dashed edge by the spout with the lip of the cup that is closest to you. Pull down on sides for secure fit and proper spout placement
  • Kids will need to bite and sip when using. The compression of the spout will open the hole and then allow liquids to be sipped out. Pull the sides of the spout to open the slit on your first use
  • Give your cup a no-spill sippy cup lid in seconds
  • Silicone top stretches over and grips top of multiple size cups up to 4.5” in diameter
  • Perfect for on-the-go or at-home use
  • Great for bringing to a restaurant to make instant sippy cup for toddlers
  • Makes it easy to avoid using plastic cups
  • Air suction keeps the lid in place
  • Warning: Do not leave a child unattended while using the lids
  • Please note: While the lids have a super stretch, they can still tear if not used properly. Use with care when taking on and off cups. If damaged, discontinue use
  • Made in China
  • Dimensions: 2.5" diameter x 3"
  • Weight: 0.04 lb.

Sippy lids for kids


Some sleepless nights I try a cup of hot chocolate to help me sleep. Sometimes it works too well, and I fall asleep before I finish.i spill the hot chocolate, have to clean up, still don’t sleep. I thought these lids would be the answer to all my sleep problems! Unfortunately, the lids are so small that the only thing they cap are small juice glasses. They are not too stretchy so are difficult to put on a glass. The silicon is so thin that they will rip with the slightest tear in the edge. They are a great idea but need to be larger and sturdier if the designers intend them to be used on adult sized drink ware.More > < Less


Did not work as advertised, very disappointed.


Did not work as advertised, very disappointed.


Had to modify these.


My 2 yr old grandson couldn't get any of the liquid out of the cup. I tried it. I couldn't get any liquid out unless I chewed on it. So I got my scissors out and snipped the spout so it had an x opening instead of the slit and made the second hole a little bigger too. Works okay, but the kids like the other product with the straw better.More > < Less

About GoSili

Silicone Solution

GoSili grabbed our attention because of their lids that make spill-proof cups for adults and kids, and for their entirely silicone travel mug. These clever solutions make taking drinks to-go—and avoiding plastics—easier and less messy.

The stretchy silicone lids fit over just about any drinking glass or cup and create a spill-proof seal. And the travel mug is made entirely from silicone, but still holds its shape thanks to an embedded stainless-steel ring that gives it structure—and that is microwave-friendly for reheats, too.

If you’re not on the silicone bandwagon yet, this material has a lot of good going for it. It’s non-toxic, BPA-free, and dishwasher and microwave safe. It won’t break down with use like some plastics can. And, by switching to silicone, you aren’t creating any toss-away waste.
