Tupperware Domed Sipper Seal

I got these as replacement lids for some ten year old tumblers. Grandson used first set ten years ago. Have new grandbaby on the way and had to replace the tops due to old ones chewed up. These lids are difficult to get on the cup but definately stay on These lids are white instead of see thru like the old ones.

These sippy lids work well on the small tumblers as well as the larger ones that come with a solid cover. They are leak-proof as long as they are not turned upside down, easier to use than the older style sippy lids, hold up in the dishwasher (I've only used top shelf for washing them) and the kids have yet to try to chew on them. I will buy more of these.

The lids are horrible! The are difficult to get on unless they are warmed and come off when cut is dropped. Do not let your child walk around with them unless you want a potential mess to clean up. They are not made like they were 30 years ago.

I've had the Bell tumblers for at least 40 years. Lost all but 2 seals/lids.Now that I have grandchildren using them, I needed more than that. I will send a couple home with my daughter to use on the tumblers I gave her, which were from her childhood.Thanks for good availability of products and speedy service.

These fit the Tupperware cups we bought 5 years ago, and it’s the only sippy cup any of my kids had success with from ages 6-12 months. It does take a few weeks of use for the tight fit to become easier, but I’d rather that instead of having them become too loose down the road. These things will last.
