The pens are available in a small, transparent Hard. With a clip can this box directly to Board / Wall hanging, very practical.
The pins should be odorless, but smell but a little benzene. On the surface of the board, the colors are pretty strong and can even be at a pace wipe dry, leaving no residue. On paper, the colors are rather pale, but they were not well developed, tried it only once.
The line thickness is 1mm, and no cap to the pins 8 hours drying out.
A practical set for the small board / Wall at home, for presentations because of the thin line width rather unsuitable.
