Very good!! Thank you!!
I really like them. They fit in my tiny mechanical pencil so nicely. Some of the colors were a little lighter than I expected but I think that my expectations aren't realistic. When I compared them with the lead of full sized colored pencils of equal color value they were very good. There are several colors and a few of leads of every single color. They are delicate but I wouldn't say that they are fragile for their thickness. They don't break easily at all when I'm writing if I don't have them unreasonably too far out from the pencil. I would definitely buy these again and intend to to keep my supply up. The seller was great. They arrived on time which is mostly on Amazon. It's a great price for the qualityof the product. A nice quality product for sure. Go ahead get them you'll see!

Multicolor.
It does what I expect for underlining. Though I must be careful because too much friction can actually tear the page. Underline slowly, sketch the underline.

break easily but very vibrant
they are great for sketching but not coloring- very small lead so breaks easy- very vibrant but cant overlap(meaning you can only make it so dark- after 2 or 3 lines in the same place it wont take in any more lines, its hard to explain but it fills the teeth of the paper very fast)

Nice but will break at an inconvenient time!
To be honest I bought these because I was sick of the charcoal gray and being in college means I take a lot of notes. I like the pop of color, but the lead tents to break at the most inconvenient time.

Worth it
Really nice, especially for sketching, but maybe it’s just me I feel like I use them up quickly!

Already bought a second time
These work very well. I got some 0.7mm from another company and they were complete trash. I prefer 0.5mm's anyway, and I was so happy that I could a single letter without the lead breaking on these. The leads have actually only broken on me a handful of times and I'm on my second container because I bought a second round already. I love color coding and erasability, so these are perfect for me!

works!
I am pleasantly surprised at how well this erasable color lead actually works! I do find that when I write with the color lead it depletes a little faster than normal pencil lead, but I like it. It does erase but the description is correct that you may need to work a little harder than normal lead.

Not a great buy.
Not very good quality. “Cheap” and flimsy. They work okay, but don’t drop one… I did and it shattered and was unusable!
