I bought these for pastel colors on my polymer clay jewelry. I have not tested it, but at first glance it looks great. The sticks are cut a little uneven, but that does not bother me. I find that half sticks are super convenient because it does not take too much space, and it has a large color panel for not very expensive. The texture was the ideal air for what I wanted to do (I wanted to scrape into a powder to dye my Fimo). I'm really happy with this purchase!
