I've been kind of trying it out on old manicures before I take them off just to see how it works, but this is the first time I'm using it seriously. It took me a while to figure out how to use it, (I kept letting the nail polish sit too long and it would dry in the stamp), but it's really easy now that I know what I'm doing!
I'm really impressed with the stamps, and they work very well with regular nail polish.
The base colour here is actually purple, but when it was on it looked black, purple, or navy, depending on the light.
