We had 2 old Hoosier jars, the really large square type, and neither one had a lid. I was pricing them on line and was not willing to pay $18 for an old "original" metal lid. So googled other lid ideas and found this site. Their largest cork lid fit one of the jars perfectly and I had been assured by my husband that both jars were the same so ordered 2 of the size 54 lids. I ordered and checked the email a short time later and they had already shipped! They arrived super fast, in great shape and they fit one jar perfectly...the other jar had a wider opening after all. BUT! We flipped it upside down and it fits perfectly which is great because they don't make a larger one and this site had the largest cork lid I could find online. My husband has an antique bottle collection and I am sure we will be ordering more corks! I have wanted to set the bottles out but didn't like the thought of having dust collecting inside them. Great product, great Customer Service!
