You get a big set of 100 aluminum oxide sanding discs for a much better price than the brand names like Norton etc. at the big box home stores, which sell for more than double the price. Good basic size range starting with 80 grit up to 240. Even the generic no brand discs at the big box stores sell for a bit more for the 100 pack. These do the job well, cover the range of grades needed for most jobs unless you're doing really fine finish work on metal etc where you want like 600 and up. But for most household prep/wood work this is plenty. It comes in a generic cardboard box, where they stack the sizes on top of each other, making it difficult to direclty access the sizes not on the top. Fortunately the box is roughly cubic in dimension, so pull them all out and flip them sideways and you can directly access whatever size you need without digging through the pile. #RankBoosterReview #Sponsored #Gocheer
