I have a Swig cup that the lid was lost and needed to be replaced. I had another lid from another brand cup that worked, although it was not leakproof. This one is and I like that. However, there must be a secret to how to get one off the cup. The fit is incredibly tight and so far, I've broken 2 fingernails trying to get the lid off the cup. It is a Swig lid on a Swig cup. If there is a secret to getting the lid off, I'd appreciate someone letting me know!

Perfect fit.

Fit my 24 ounce Swig

perfectly!

I buy one every time I grab a new swig. These are the best. They seal in my drink really well, and work better than the lids than come with the swigs IMHO.

Fast shipping and great product!
