Rikagaku Dustless Chalk Holder (DC-CH)

for the serious blackboard worker, this is the best chalkholder for the best Japanese chalks. Be careful about sizes - the slight differences in chalk diameter mean that you have to fit the chalkholder to the chalk carefully, but for those dream-like good Japanese chalks, this is by far the best and affordable chalk holder. Buy two so when a colleague steals one from you, you will have a reserve to use until the next one(s) arrive. And don't let colleagues near your desk because they will steal your chalk and your chalkholder. Trust me, they will. And since you will keep this in a jacket or trouser pocket or your purse, you will come to appreciate the cap, too.

fits standard chalk very well, works well, high quality.
