The Roll Roy 2" Mini Roller Superfine Sponge "€ś Straight is powered with the goodness of science and experience, from its makers who have been in the business since decades. The roller is composed of a very high grade foam, that is both soft and very dense, so as to hold on to an increased amount of paint in every coat. The softness of the foam makes sure that maximum amount of absorbed paint gets released with every coat of the roller. The roller runs evenly on surfaces with high contours and uneven terrain.
