Customer Reviews


These lids, along with the cups and straws are a great compliment to my business. They are of great quality and are a great price. My clients love them and I do too.

This cover is just the right size for the compatible cup. The snap and seal keeps the liquid in. The quality is quite durable. Good buy!

Hermione F. from SHARON on 01/28/2017

I love this lids for the go, I usually prepares smoothies or iced coffees and walk out. It's cheaper than buy them outside. The lids work perfect with Item #: 999TP22. Great quality!!

Diana M. on 08/11/2016

Great sturdy lids that we bought to match our #999TW12 cups. The slot is easy to fit any kind of straw through and the lids fit snug. Well constructed as others we have bought previously had many defects including not being able to fit a small straw through the slot opening.

Anna M. from Dream Thread LLC on 08/03/2016

These fit the Dart Solo Ultra Clear 12oz. cups perfectly. They did the job for my daughters lemonade stand. Held up pretty well. good price

Brianna W. from Dcreated Boutique on 06/24/2015

Great, sturdy lid. So handy for those car trips and whenever I want to prepackage drinks for the kids or a party. I really like these as they snap on easily. No second guessing if they are on correctly. A real top quality product.

Debra M. on 04/18/2015

I love these lids! Some lids are difficult to get on but these are not! They work great, fit snug and don't leak out of the sides. I highly recommend these.

Diane A. on 07/21/2013

These are nice sturdy lids, they go on easily and work well. With the cup they make an attracive way to serve our cold drinks.

Jeanette H. from Taste & See Coffee House on 05/22/2013

These lids are higher quality and will not easily crack or break! Easy and secure way to offer soft drinks! Easy to use with clean cut straw slot!!

Eric K. on 10/11/2012

These lids are super sturdy and fit perfectly. The only thing I dislike is the small lids only fit the small cups, whereas the larger lids fit a couple different sizes.

Jennifer M. from Downtown Java on 02/21/2012

Nice lids for a nice price. Seals the edges of the cup well so there is no spilling of any drinks. Too bad it's not all one lid for all sizes though!
