Sometimes the simplest designs are the best, this is definitely one of those occasions, and I cant believe no one has thought of this idea before, the Eraser Brush.
A genius idea if ever we saw one! In one end of the solid wooden block is a pencil eraser, and in the other a natural hair brush for sweeping away all of the rubbings. Simple, unbranded and utilitarian. Every household needs one!
Very cool, a great design, if you want one of these cool Eraser Brushes, they are available for £7.00 about $11.50 from Present & Correct.
