OK, they are not the "Offical" seal. So if you are planning to try to get into a Poker Tournament
you will get found out and in major trouble.
But for magic, I have never had anyone
challenge them. Do be aware they come in colors, and make sure they match the decks you will be
using.I use the black.
I'm use mine for an effect that has me make a false back for a box
with a Double face card and the seal is cut out- so what is said on the seal is no issue.
Good to have in the toy box for those Ah HA! moments.
