So, I definitely got what I paid for here. Lots of colored pencil leads, in convenient carry cases, but unfortunately, they seem to break very easily, at least compared to what I was used to, which was the leads in both the Pilot brand and Paper Mate brand erasable mechanical colored pencils. I think I'll probably get used to it, but I do wish I had just spent the extra money and bought the name brand refills.

I've bought this lead to use for undrawings and sketching. From my experience it is very brittle. Even with slight pressure the lead constantly snaps. Which is annoying because it draws so light on the paper I need to apply pressure to darken it up. Sometimes just putting it in the pencil it crumbles between my fingers. Also when I try to use other lead on top of it, the leads don't seem to mesh. I'm not sure what it is. Watercolors seek to work fine on top. It also does well with erasing. Probably won't buy this product again.

Nice for light sketches, quite difficult to get into the pencil and it takes a second to find the right pressure on paper. Pigment is pretty damn light.I use one of those fancy metal mechanical pencils ( and the lead wouldn't fit through, so that was not epic. But its worked with most other that I've tried.

They break really easy and they are very dull

The replacements work only if you’re writing or drawing lightly. Any kind of pressure and the lead snaps.
