Review on Enhance Your Professional Magic Tricks with Close-Up Accessories: The Ultimate Magician's Toolkit by Alex Pollard

Very cool but also very scary. I strongly recommend that you do not give this to a young child. This item has enough spring force to pierce your eye or knock out your teeth. The edges of the expanded metal are also razor-sharp, and despite being careful, I've cut myself. Reshaping this item into its original small form is also quite difficult, and usually happens when you're at your most vulnerable to cutting yourself.
