I bought this new and it has worked well. It has two glass plates currently with 120 and 80 grit on one and 400 and 200 on the other. It has extra sand paper for those and an additional course abrasive kit. It has the slotted disk as well and some extra paper for that and the small squares to replace the piece in the tool holder section. I am selling this to fund some other tools I would like to purchase.
