Not great at all.

I just really didn't enjoy this product at all. The pigment is non-existent. I tried applying another layer to make it more opaque, and I do admit that it dried quickly so that wasn't problematic, but it was still more of a light grey. And I didn't realize that "metallic" meant a few chunks of glitter. The tip is very thin, and ensuring it's shaken is vital if you're dead-set on using this product.
