R.s.Magic Tricks 555 Mvision Marked Deck Cheating playing cards with hidden signs on the back  (Black)

At first sight they are just the ordinary playing cards. But this is only at first sight. Actually, they hide a small secret. Every single card is marked on its back. But naturally, this is very hard to notice if you don’t know where to look. And do not worry – no one around you will be able to read the symbols – they are really small and well hidden in the drawings at the back of the cards. Their little secret will be known only to you because the cards are no different than any other ordinary playing card decks
