These awesome color changing tumblers with matching straws are 24 oz. I can personalize with any color permanent vinyl you want. The standard vinyl color cups are $8 each. If you want holographic vinyl, the cost is $10 each. The cups shown  are holographic vinyl. The personalized cups are not available, but I can make your just like them! I can also turn the vinyl vertical like the 2nd photo shows. Please specify the color vinyl you want and your name in the custom box below. The larger the name, the smaller the font will be. I have 2 of each color cup at this time.
