Tamiya Sanding Sponge Sheet 400

When there's real material to remove — chunky mould lines, sprue nubs, heavy seams — you start coarse. Tamiya's 400-grit sanding sponge sheet does the shaping work, its flexible foam base moulding to curves and corners a rigid block would skip straight over. Cut it to size and sand wet or dry on plastic, wood and metal.
