Colors are inaccurate, but works well
Instructions are poor and the colors are definitely not as advertised (the lightest one is very coppery rather than light brown or blonde), but they actually work well.  Took a little trial-and-error to figure out how to use them, but they hold very securely and I’m actually pretty happy with how they make my hair look.  They work best for me without a ponytail (my hair is layered and the shorter pieces fall out as I’m rolling the bar up with a hair tie in), so I just roll it up with my hair down and it holds well without any other products.  Doesn’t feel at all like it’s going to slip out.
