THE YOKEN TWIN marker has a borad tip at one end (line width 7mm) and a fine tip at the other (line width 1mm). Hence, a single maker gives the artist an infinite variety of line possibilities.
This markers is virtually odour free. It has the added advantage of being able to be used on photocopies without affecting the print.
The ink base is composed of non-poisonous alcohols such as ethylalcohol,isoprophl-alcohol and buthyl-alcohol; no toxic materials are greater than that of pencil shaped makers and pens assuring the artist satisfactory ink yield.
Penetration into paper surface is less than is usual with other permanent markers.
Even if the cap is accidentally left off and the pen tip dries out the YOKEN TWIN can be returned to a functional condition by simply replacing the cap and leaving for 2 or 3 hours.
Colors may be laid one upon the other. Use in conjunction with other material, such as pastels, is totally appropriate.
