Hermes Hand Block for 150mm Discs

What a good idea, this hand sanding block has a velcro base and sides to allow 150mm (6") velcro discs from an orbital sander to be wrapped around, very comfortable to hold with finger moulds, constructed from polyurethane foam it is also very robust and as it is bright yellow not easy to lose in the workshop! Overall sanding size 150 x 85mm excluding sides.
