I know this is not chip related but they are from Casinos. Trying to find these a good home. Four for $1. Pick and choose. I will fit as many as I can in an envelope and ship non machineable anywhere in the world. Domestic postage and International postage will vary a little but I will ship as cheap as possible. Shipping will be extra on top of the $1 for any 4 matchbooks. All books are unstruck and have had the matches carefully removed. Send me an email with any questions. Thanks
