PrangAmbrite Colored Chalk for Paper, Tapered, 3.188 x 0.438 Inches, Box of 144 Sticks, 19 Assorted Colors (51000)

I have counted all of the chalk in the box, and it came to 146 'pieces' of chalk. Each 'piece' is about 10-30% of a 'stick' of chalk. Mine also came with a loose piece of metal in the box! This is clearly a return item, with a piece of metal thrown in to make it seem heavier than it actually is. This will be my first return ever. Very poor quality.

ご丁寧な対応のショップ様でした。商品も良かったです。

Good quality chalk, but just received via currier and opened the box to find 102 pieces of 144 broken and many as small as 1cm. The other box of chalk I ordered was perfect with no breaks so not sure how this was so so damaged (box looks in perfect shape). Kids were sad to find their new homeschool chalk so damaged.

Love the vibrant colors! A few pieces came broken but it does not affect use. We've only used them on art paper so far but it spreads nicely with your finger if you want a "watercolor" look. I purchased the small package but now I wish I would have purchased the larger one. Will do when these run out!Edited to add: They work better when broken. I ended up breaking them all on purpose. I have also used them on a chalkboard since I posted this review and they work great (though not as vibrant as they are on paper.) They also wipe off fine.

This chalk is incredibly soft. Even though it's meant for artwork on paper, we use it as chalkboard chalk. The colours are amazingly vibrant (even the black!), and despite its fragility it holds up decently well in the hand. I highly recommend this set for both art on paper, as well as science and mathematics on the blackboard.
