These top quality abrasive sheets, made in Switzerland, measure 70 x125mm and come in packs of 5 sheets.
 
They use an aluminium oxide abrasive, blue fired to remove impurities, for a longer lasting and clean sanding action, and the knitted fabric backing allows the dust generated to simply pass through, giving a longer working time without having to de-clog the abrasive.

The sheets are very flexible and fold and bend easily to mould themselves to the shape of the piece being worked on.
