Rikagaku Assorted Colors Dustless Chalk, 6 Pieces (DCC-6-6C), red, yellow, blue, green, brown, violet

I'm no mathematician, so I don't care that much about chalk. However, I do have a terrible chalkboard, and the crayola chalk I was using was scratchy and wouldn't stick to some spots. It was effectively unusable. I bought this chalk and the difference is night and day. It writes smooth and wipes off easy, and there aren't any spots where it doesn't stick. Now the crayola chalk feels like a burnt stick covered in glue and dirt. I haven't tried other brands, and now I probably never will. This stuff is great!

I really like the chalk, but this package has two of the six pieces broken in it. One is just small enough, that it won’t hold in my chalk holder.

It’s is chaulk that I expected a few broken but will work fine

Much better than Crayola or Roseart but not as good as Hagoromo. The dust reducing coating is a nice feature and it writes very smoothly and erases very well.

Wonderful chalk. I bought a very cheap chalk board that is not smooth at all, I'm honestly hesitant to call it a chalk board it might actually be plastic. Anyway, it's hard to write on and erase, I have tried several brands hoping to find something and am super happy to have stumbled across this brand. It writes soooo smooth, even on my bumpy surface. It comes off easily and has made using the chalkboard much easier. Extremely happy with this product and will be buying more when the first set runs down. Also, I noticed some reviewers complaining about broken chalk, mine came whole and since the plastic container the chalk is shipped in is spaced for each individual piece of chalk, I'm gonna assume rough shipping was the cause of their problems and not the chalk being of poor flimsy quality.

I like these. I want to love them; however, they are messy. I don't know if the Japanese have a different definition of dustless, but these are far from it. Make sure you have a holder for them and be aware that they are thicker than standard chalk.

Chalk arrived as described, 6 pieces: 4 white, 1 yellow, and 1 pink. Though some reviewers had issues with chalk arriving in pieces, all 6 pieces were unbroken. I've been using this chalk 2x week since the beginning of the winter semester (about 3 months) and I still have 1 white piece, half the yellow, and half the pink left.This chalk is softer than standard chalk, meaning you need to have a lighter hand when using it, else it can break. Writing lightly still results in a highly pigmented and visible mark. In addition, the softer texture means no horrible chalkboard screeching!Also, this chalk doesn't last as long as long as standard chalk, but it is worth it to me to have dustless, screech-free chalk!

I love the size of these chalk pieces. My son can use them easily and fit his hand perfectly. (He is 2 1/2.) The color on the board is very bright and comes off smooth. They are not dustless however and one was broken when we received it. I do like them however and will likely purchase them again.

These chalk sticks are a little shorter than standard chalk, but the chalk is one of the better Japanese chalks around ... and unlike most that become idiotically expensive by the time they get over here, these are relatively affordable. For professional mathematicians who work the chalkboard these are are certainly an improvement over most "dustless" chalk.

Asides from taking a long time to ship, I have really enjoyed this chalk. There is a coating on the outside to prevent your fingers from getting all chalky when holding them and they definitely produce a lot less dust than common brands. I wouldn't say they are dustless, but I have not found anything better.

描きやすいです。自宅の壁を黒板クロスにしたので購入しましたがこれはクロスの方が凹凸があるためチョークの減りは早く感じます。白色がないので白があると大変満足です。
