Professional Tailors Chalk Triangle Tailor's Fabric Marker Chalk - Sewing Notions & Accessories（20 Pack）

I got these chalk triangles for tracing patterns on dark fabric. Worked well enough for my purposes, the lines are thicker than other mediums.Quality was excellent for what I was expecting after reading other reviews. It was well packaged in bubble wrap inside a box, arrived with only one broken piece. Not bad considering it was bundled together with other items in a larger box for delivery. The plastic storage case had a rubber band around it. I tied the rubber band back after I was done with the chalk. The case lid was a bit loose and I don’t think it would be closed securely enough without the rubber band.In the third picture attached, I traced the pattern for masks using 3 different mediums. The chalk (on the right side of the fabric) had the thickest line. What was lost in precision was gained in visibility, so it’s a trade off I was expecting when I ordered this. The precision can always be adjusted slightly during cutting.I was debating between a 4 or 5 star for this. Based on the quantity of chalks you get and the condition they arrived in, I gave it a 5 star just for the value of the whole packet. I bought a few other alternatives and I think this had the best value.

Always wondered what those tailors were using to mark up suits when I had them made, so I jumped on these after stumbling across them on Amazon. I can't imagine there's much difference in quality in the actual chalk, but the dimensions on these are just right: not so wide they make huge lines, not so thin that they break too easily. The choice of colors is great: at least one color will always show on whatever cloth you're using. The case is a nice bonus: holds the chalk securely. (The latch isn't great, but it's fine if you wrap a strip of velcro or a rubber band around it.)

I was very disappointed in these chalks as they came broken into small pieces. I got a replacement but these chalks are TERRIBLE!! DO NOT BUY THEM!! They are thin and break with the very slightest pressure. They are one of he worst products I have ever purchased from Amazon and I have bought a LOT over MANY years.

The media could not be loaded.  They answered that it can be removed with steam. It does NOT!I hope no one ruined their project with false advertising. In my video, you can see the camera fogs from all the steam i used and it did not remove.

I received the chalk, and several pieces were broken. It is still usable, but it was annoying. The case they packaged it is a nice hard plastic, so I guess the jostling around in shipping caused it. I tried the chalk, and it marked easily and came off easily.
