I had a problem.
Every time I used my mason jar, AKA my favorite drinking glass, I didn't have a lid. Then when I was driving or playing with the kids I would spill my yummy iced coffee. Boo. That's just not OK.
But did you know that the lid to a Parmesan cheese container fits almost any size mason jar...just not the big size, but I'm on it, I just haven't found the right lid yet. Ha!
So enjoy your mason jar glass on the go!
You deserve it.
