A hard red-brown clasp polisher made with very fine grit silicon carbide. It can be used on porcelain or metal, but it is best for polishing non-precious and chrome-cobalt alloys in the dental lab. Similar to the red polisher, but longer lasting. This is the same as the Keystone Superior Hard Red clasp polisher. 100 per package. The size is .25” diameter x .88” length. Made in the USA.
