日本理化学 Dustless Chalk 72pcs, Yellow

My class likes doing work on their science lab desks with chalk. Buckle in for a dramatic story: I began the year and found a box of chalk left by my predecessor and had been using it. I got more chalk through the school and it was crayola an du septic, and it is TRASH (see top line of photo). I knew I just needed to order more of the other brand, which shall remain nameless. Why? Because it is the best chalk ever made, but they seemed to have stopped making it in the SEVENTIES, and I am gatekeeping it from you good people. See bottom line of photo for the most perfect chalk ever. Distraught, I went to Amazon to find a replacement and found this. Lab tables are less writeable than chalkboards, so they require softer and more pigmented chalk. I was explaining my chalk woes to other teachers and one gave me a piece of Hagoromo. See the photo for the comparison. This brand is very similar! It writes well. My second photo demos what all of the chalks look like after one (1) swipe of an eraser (not back and forth) to give you an idea of eraseability. All of them erased very well once I gave it a couple more swipes.Hope you enjoyed this journey with me. Happy chalking!

My son says it’s great. It’s breakable as far as functionality but he says it lasts a long time

Wide stick, coated to help limit dusty fingers and has a nice feel while writing: Lines are clear. This chalk does not scratch or mar the board surface.Are you looking at this as a replacement for Hagoromo?: Rikagaku chalk has a slightly smaller circumference and is about 1/2 inch shorter than Hagoromo. It is packed in plastic trays, rather than nestled in little foam beds like Hagoromo, so there seems to be more breakage in transit. Also, I can't explain why because I'm not a chalk production expert, but this chalk is definitely dustier than Hagoromo.Overall, if you're a chalk nerd like I am and found Hagoromo chalk oddly satisfying ... I think you'll derive nearly the same feeling from Rikagaku.

If the manufacturer had packaged this chalk in a sturdy box or even taped the box closed, we would not have had a mess when we opened the package. Most of the chalk was out of its box, about a third was broken. Also, this is tremendously dusty chalk. We both had to wash hands after handling only a few pieces. Use with wipes handy!

Beautiful yellow color easy flowing chalk.

The chalk was NOT dustless and all the pieces are broken. Would not order again or even slightly recommend.

Who knew there could be such a difference in chalk? I got it for my classroom teacher after seeing a news article in class. I bought it for her as her Christmas gift and gave it to her early. I bought myself a box, as well. I make mini-chalkboards out of metal trays. The quality is superior to anything I've ever used. It's practically dustless, writes brightly and clearly every time. The large quantity will last me quite some time and is well worth the cost. I definitely recommend this quality product.

There was no effort to protect the box with bubble wrap or cardbord, it was just placed in a soft Amazon bag. The chalk itself is good as I have other boxes of this brand.
