The precision pencils are available in 5 configurations:
1.) carbon and fiberglass tip
2.) brass needle and brass scalpel
3.) brass brush
4.) 5 tips including all of the above
5.) ALL 5 tips PLUS 5 pencils (so you do not have to change out the tips since each has its own pencil).
We sell all configurations in our store and we also sell refills for all the precision pencil sets.
Do not apply too much pressure on the tip in order to avoid damaging the coin or relics.
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.
