Grinder sponge

These sponges are made to fit perfectly and distribute water evenly, really seems to minimizing messy water over spray and the price is so affordable I bought several !

A little large.

The space in the bitsert is fairly small and the sponges are too large when wet. When it’s time to replace the one my new grinder came with, I will be cutting it down before I get it wet.
