I have bought sand paper plenty of times from Grizzly, I have never been disappointed in their products. They have course up to very fine. Sanding between coats is very important to a showroom finish. And they hold up, without fail to wet sanding. So if you want a great finish to your woodwork projects like I do, this is the sand paper what ever grit you need. Also it is cheaper to buy in bulk. I usually keep 400 sheets of each grit, and reorder when I get below 100.. an example of what I keep are as follows, 220, 240, 300, 500, 600, 1200, 2000. This is plenty for a very smooth showroom finish.
