Review on 🍊 Revamp Your Regular Mouth Mason Jar: Introducing Orange Jarware Oil Cruet Lid by John Lewis

I was delighted with this product. I've been waiting for it to be back in stock. I can't get it to snap into the metal ring even after holding it under hot running water. I can't find the right box either. I have several different brands of standard mouth cups and they are too big to fit in any of them. If I can eventually build it into a metal ring, I still can't use it. Bought 2 and both had the same problem.
