Paul Gordon's Spectral is impossible to imagine how so much magic can be derived from so few cards. It's a thin natural-looking packet, but just look at what happens. Five Jokers are cleanly shown to have faces both sides. Then they all magically get blue backs which instantly change to red backs. Nice presentation, too. Supplied in Bicycle/USPCC stock colored Jokers as per the promo/trailer video. Oh, no rough/smooth, no switches, no lapping, no kidding. WYSIWYG.
It's a real eye-popping worker! It truly will become part of your EDC and you'll use it a lot! Online video tutorial included.
