All of my custom cards are crafted with real pokemon cards for bases! Depending on which card you choose - I use english, Japanese & vintage old back Japanese pokemon cards! The chosen artwork is printed on thin fine art paper which then gets a transparent holographic vinyl overlay placed over it. The now holographic card art print is pressed under a 7-ton hydraulic press! This gets any air gaps out of the holo and makes it shine much more vibrantly! Finally, this print is then fixed to the card back with a mess-free adhesive & trimmed to perfection! All cards are placed in standard sized clear sleeves & toploaders!
