Just doesnt scratch right it takes the number off.

This product was not capable of doing gradual whiteout or whiteout period and that is what it needs to do

I am an artist and NEW to the scratchboard scene. After working on this for about a year now I have found that if you have the right tools, it will really make a difference in your art.

No instructions. Tips seem hard to change, and unsure as no instructions.

There are visual stress marks on the top of the pen where the cap attaches to the pen. THe cap constantly pops off alowing the brush to recract back into the pen. These are to cheap to be practical.

If you work on electronics, this is a must have.

They are of the quality that you would get as a prize from Chuck E. Cheeses.

This was exactly as expected and works well.

Fantastic idea I havent used yet seem to be a little flimsy might break easily I purchased to clean corrosion out of AAA battery compartments on camera equipment. I love the way you can extend and retract the brush Not sure how the plastic will hold up with electronics cleaner spray might melt or the metal tip hold up with simple green or other water based cleaner might rust

Product does come with two metal plus one plastic bristle brush pens and replacements. The product is cheaply made so taking the existing brush to put a replacement literally destroys the pen itself so it is pretty much impossible to use that replacement with the existing pen. The brushes are also very weak and flimsy so they dont offer much brushing. I gave it three stars because the metal brushes are more useful but not much.
