Pressure Sensitive Abrasives (PSA) have a pressure-sensitive adhesive backing for easy application and removal. Look here for PSA Sanding Discs, Disc Rolls, and Abrasive Sheets, as well as the Backup Pads they require. 

We also supply a wide array of 3M "Stikit" Accessories, like sanding forms and a handy Disc Dispenser. Look here for the Air File Shoe for "Stikit" abrasives - you will find all "Stikit" hand sanding forms in the Hand Pads, Blocks & Boards section of this Sandpaper & Abrasives Web Category.
