This set of our wooden Conservator Pencils (also called ``Crayon à Gratter``) includes 4 pencils: fiber glass, carbon tip, scalpel and brass tip. It's perfect for all beginners !

This set includes 6 pencils: fiber glass, carbon tip, scalpel, brass tip. It adds a steel wool brush and a brass brush to clean your coins even faster. It's a more complete pack. Only the Multipen is more versatile.

The vise will block your find during the cleaning process without damaging the edge of your artefact/coin thanks to it's soft wood made. The USB magnifier with LED allows you to better see your find.


The brass brush will wipe the first layer of dirt. Use gently in order to avoid scratches; we recommend to change tip as soon as you narrow down to the surface of the coin/artefact.

The steel wool allows to accurately clean a coin even between letters and asperous areas. Contrary to other pencils, our longer refill lasts much longer thanks to our stiffener manufacturing process

The glass fiber tip will clean your bronze artefacts without damaging the patina. It's also very effective on all sorts of metals as it's the softest tip available on the precision pensil.

This hard carbon tip is dedicated to removing dirts that the glass fiber will not be abale to clean. It's effective on all kinds of metal; in order to avoid damaging the patina, use cautiously on bronze.

The scalpel is meant to get rid of the toughest piece of dirt or crust. The scalpel is more efficient if you use a pull-out gesture rather than a scratch motion. As it's the hardest fitting, it has to be used with extreme caution.

Being very thin, the brass tip is the most accurate tool available on the precision pencil. Use it in the finishing process to clean areas that cannot be reached by other tips such as letters of a caption.


  1. Try to use use circular motion while cleaning
  2. Do not apply to much pressure on the tip in order to avoid damaging the coin or relics
  3. Do not apply on a wet coin or object as it may damage patina
  4. The harder the tip is, the better it wil get rid of hard deposits and dirt.
  5. 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 hard tip or brush
  6.  If you have to clean a coin with patina, use the fiber glass brush as it will  not damage patina .
