I don't know why, but I got 4 of these mailer cards in the mail.
Front and back shown in image.
They are heavy laminated cardboard.
The redemption card breaks out and is the size of a slot card.

One was addressed to Lawrence, one to Larry, and one to Pang.
The 4th was to a John Wong.
I think their data base needs updating, not that I'm complaining.

I could only redeem one with my players card.
The Free Play Chips are oversized and the same from last year, see scan.

If you're a collector of these things, email me.
Will sell oversized chip for $7 postpaid, will include one of the mailers, sorry I only have one chip.
Will trade one of the mailers for a casino room key.
