Personalize your tumbler with your name and/or your significant other’s name. These are 12 oz. Polar Camel double insulated tumblers. These ship in a USPS Medium Flat Rate Box. Maximum of two per order please. Orders or three or more ship in a Large FRB ($20). I will refund shipping costs if I have a smaller box available that the tumbler(s) fit in. Backorders allowed. Please allow up to two weeks for delivery as I periodically have to reorder blank tumblers.
