The ring on my tumbler was starting to rot, so I needed to replace it. I did not need a new lid and I did not want a new tumbler. I have the Ozark Trail 34 oz tumbler, with the open slot lid. If you have ever taken the seal off of your tumbler to clean it, this will go on the same way. Just watch your orientation with the flange. I am very happy with my purchase!
