I've not received the cards yet but the tutorial is superb, nothing to go wrong with the gaff cards,
nothing to fail wear or snap.The tutorial is well explained at a pace that you can follow, there's
no dodgy moves or slights to go wrong. After the change, then change back, it's explained how to
finish clean, with all cards can be examined. A nice final touch for any sceptics or anyone that may
suspect gaffed cards.
