Illadelph Mini Base Bumper (Black) NEW

As far as I know, there are only two sizes for illadelph base bumpers. I have another one that is twice this size so I assume that this is the mini. I’m not exactly sure what this fits and doesn’t fit, the website isn’t that specific. Measure about 5 inches but is very flexible so it should fit most Illadelph beaker bases, maybe not a heavy hitter but again I’m not entirely sure. These retail for $19 online.
