You know, it's not too bad of a concept! I am not the best at stamping. I just don't see how you would know it was stamping the entire nail. Also, you could only use the plates it comes with.
I don't see how it'd work very well if you want to cover your entire nail with a design...especially if you have curvy nails. Stupid!
That just seems like way too much work to me. I'd think you'd have to remove the plate and stamp after every use to clean them, like with regular stamping.
