Yagote Silicone Sippy Cup Lids, 5 Packs Elephant Spill-Proof Sippy Cup for Babies, Toddlers and Kids

Q: What cups do these go on?

Any cup you have. They are not made to match any particular brand of cup or glass. We have used them with regular glasses, closely supervised of course!!

Q: Will these fit comotomo bottles?

Sorry, I have never used those types of bottles I use then on the small metal cups with silicon sleeves featured in Amazon. It’s a tight fit for that mouth ( about 8.5” in circumference).

Q: Is the hole on top of the elephant for a straw?

I suppose you could put a straw in the opening…my daughter just drank from the spout without a straw.

Q: Do these fit on life factory narrow 4 oz and 9 oz glass bottles?

They are made to fit over cups for children.so I wouldn’t recommend putting them on glass bottles. However, they don’t stretch out a lot, so it would depend on how wide the opening is. They fit well on a 3 inch opening. Not any wider.
