I had previously purchased cups from a local retailer but they have constantly been sold old. While these cups were slightly more expensive than the ones I had previously been purchasing they are still an excellent value considering I could not find them at this price point after an extensive online search. I am going to answer the question in this review that I had when I ordered (but there was no review to answer it) and it was my main concern ordering a product sight unseen. YES, the lids snap on tight!
The order arrived pretty quickly also and everything was nicely packaged. I immediately placed another order the day mine arrived, not because I needed more cups but because I ordered the wrong size! LOL
