As of this writing USPCC has gotten pretty paranoid about their copyrights. You can't get gaffs that
alter the standard "rider back," and you definitely aren't going to get seals that say "THE U.S.
PLAYING CARD COMPANY" which you could go slap on any deck. The previous reviewer is correct that
this is bothersome for perfectionists, but it is going to fly right past laymen. I've even gotten
the comment "but the deck was still sealed," so they clearly looked at the seal and had no issue
with it.
These are the standard size, which is nice; if you peel off the old seal and
re-seal with this, there isn't going to be any exposed "sticky area" to give you away. Be sure to
press firmly and hold for a few seconds. I also recommend that you leave in the advertising cards
etc., which is a nice subtlety; and using this with the Wonder Sealer for a truly convincing
"factory sealed" deck.
Some magicians have taken to printing their own seals, but for this
trivial price, the convenience of buying these is well worth it to me.
