This is a set of 3 sanding pads, consisting of 1 of each of the individual sanding pads: 1 x 800, 1 x 1000 and 1 x 1500. By buying them in this pack you can save some pennies, 100 pennies in fact.
These sponge backed sanding pads are excellent to use with your metal clay. They are soft and flexible so wraps smoothly around your piece. I love these, couldn't be without them! Use them dry on the clay, or wet on the fired metal for a beautiful polish. Rinse after use and they'll last a long time. I usually cut them up in thin strips which are easier to work with. Each pad is 140x115x6mm.
The tech bit:
Abrasive Grit - Aluminium oxide
Binding - Flexible grit binding
Foam - EVA (Ethyl vinyl acetate), PU (Polyurethane)
I found this sanding pads much easier to use than using files.
