This rubber block is extremely handy on the bench, for filing, hammering, and other uses. Made of a tough, firm, vulcanized rubber measuring 4" X 4" X 1" (10 X 10 X 25mm) to give the user an excellent surface. It enables one to remove dents and straighten metals without the fear of scratching or distorting, and can be used to secure parts for filing as well.
Love the size! Makes stamping so easy!
