Nippon Rikaku Dustless Fluorescent Chalk, 4 Colors, DCK-72-4C, 72 Pieces

These glow really well under UV/Blacklight! Loved that they didn't leave much residue on my hands. I was concerned about how small they were, but they lasted surprisingly long.We used these for Halloween and couldn't be happier. We also put them out for our son and neighbors kids and they had a lot of fun. 10/10 would buy again.

I’m sure this would’ve been great if I had received it in good condition. 35 sticks out of 72 arrived broken into little pieces. Disappointing and a huge, powdery mess to deal with.

good

授業で使用しています。もう手放せないと思います。チョークで書く黒板で授業をする限りは。

自分の授業の時には必需品です。ダストレスなのでやや硬めですが発色と，授業後に消す作業を考えると断然，このチョークのほうがいいです。白は単独で購入したのですが，カラーバリエーションも板書には必要。無くなる前にまた購入します。
