All of my custom & proxy cards are made with real Pokémon Cards for backs! Mint, pack fresh, english pokemon cards are used for the majority of my cards. I use real vintage old back Japanese Pocket Monsters Cards for my vintage japanese replicas/mint, pack fresh, Japanese Pokémon cards for current cards. All non-holo cards are made using a semi-gloss finish that feels and looks just like regular cards! My holographic cards are made with fine art paper and vinyl - they have a smooth, glossy feel to them. The holographic cards are mainly waterproof on the front. If they get wet the holo may fade and then reappear when dried! I place all cards in clear ultra pro sleeves & toploaders. They are then fastened to a slab of cardboard and sealed in a waterproof bag with a couple freebies! Orders generally ship within 1-3 business days using tracked USPS First Class shipping! Your tracking number will be automatically emailed to you once I print the label! Contact me with ANY questions OR custom print requests! Looking for authentic cards?
