I've used these scissors over 100 times in my shows. It always gets a good response. Like another reviewer said, these aren't for cutting, but I see no problem with that. I bring them out and expect the spectator to cut with them and the fun starts.
I give it four stars rather than five because they are a bit expensive and because even after using this for years, it still takes some concentration to open and close these is a smooth and natural way. I always get them to work and it always looks natural, but it requires a bit of focused attention. From a spectator's viewpoint, it is impossible to figure out how to open or close them.

This are good luking scissors, is realy hard to find how it works. This are not infalible, but do the job. The only bad thing about this scissor is that you can't cut anything like otrher cut and no cut scissor, thats why this are overpriced.
