You are referring to the 67.7 mm chip racks. They fit 100 Paulson chips perfectly, in five rows of 20 chips each.
They're slightly different in size the racks we use here for Key West chips, and more expensive. I can order as many as you need and have them ready to ship to you in about a week. Our price would be $2.99 per rack.
Really? A branded Paulson rack! I've never seen one. My casino supplier has two sizes, but only says that their 67.7 rack "fits 100 Paulson chips perfectly." If it said, "Paulson" on it, I'm sure they'd say that.
My guess is if they have the Paulson name on the rack, they're coming from Trademark Poker, Paulson's retail distributor. Trademark would sell those to me for the retail price, so it would be less expensive for both of us for you to contact Trademark.
