This is essentially the retail site for Klingspor abrasive company. They also retail many other items for the woodworker.
I've bought their sandpaper multiple times, including some of their bulk boxes. Every time, they have responded well, the sandpaper is excellent, and pricing is right. There have been some complaints about the bulk boxes being bad paper, but Klingspor will replace them if asked.
THIS IS ANOTHER GREAT WEB-SITE TO ORDER FROM, FOR ALL THE WOODWORKER'S LIKE MYSELF. EXCELLENT QUALITY&SERVICE...
