6-Pack of Conservator Le Crayon a Gratter Precision Pencil Refill Set - 1 Brass Brush (No Pencil)

This brass brush fits both the Multi-pen cleaning pen and the Precision Pencil and allows you to quickly remove the surface layer of soil. 

The precision pencils are available in 3 configurations: carbon and fiberglass tip; brass needle/brass scalpel; and brass brush. We sell all configurations in our store. And we also sell refills for all the precision pencil sets.

Try to use a circular motion while cleaning.

Do not apply too much pressure on the tip in order to avoid damaging the coin or relics.

Do not apply on a wet coin or object as it may damage the patina.

The harder the tip is, the better it will get rid of hard deposits and dirt.

The best tool to get rid of the crust is the scalpel; when you reach the surface of the object, use a softer/more accurate tool such as a hard tip or brush.

If you have to clean a coin with a patina, use the fiberglass brush as it will not damage the patina.
