Avery tabbed notebook dividers, monthly. Seven unopened sets (two with colored tabs, five with white).  Take what you need and I'll distribute the rest to other posters. I got them in 2015 but they are unopened.  Without opening, I have to guess that memory is correct, that the tabs are plastic coated, and the strips of ring holes as well.  I ate them for breakfast when working, and had illusions of needing them in retirement. HAH!
