This is a pair/2 of Revlon Cosmetics ceramic mugs. They came out with these in the 1980's as a promotional item. I think it was originally a set of 4 that you got with a purchase. I believe these are 12 ounce mugs. I'm  offering FREE US SHIPPING on this item!!! NOTE: Three cats wandered into my gravitational field and my heart. They live indoors only and even though I try my best to keep them away there may be one or two...or three cat hairs included. If you are allergic please don't buy.
