Review title is Poor quality crumbly pencils [SEP] These are very poor quality pencils compared to other brands I have purchased on amazon of the same type. I use them for drawing the eyebrow shape on clients before microblading. These pencils crumble easily and need to be sharpened constantly to maintain any sort of point, and because they’re so crumbly it’s difficult to sharpen them, therefor I estimate I could complete about 3 clients per pencil.
