This is a fantastic stripper deck. It is is made by Bicycle for Magic Makers and comes factory sealed in the red color. When I first opened it and looked at the cards I could not really see any size or shape difference or obvious taper but then I tried the basic trick with them that you find on youtube and everywhere and it worked perfectly over and over again. Makes you an instant magician. I don't think anyone just looking at them would notice anything odd or different about them which is great. I've read reviews of different stripper decks that stated they were too obvious or didn't work etc. Not these. These cards make you look like you have very serious sleight of hand skills. Great product. Make sure you order them from Rock Ridge Sales - they are excellent and stand by their stuff.PS: You can find the 10 bonus tricks it comes with at a website that is listed on the packing material.
