These charming wine glasses depict a pair of dolphins playfully jumping in front of a palm tree.  These delightful glasses are made with temperature changing vinyl, so they are blue at room temperature, but add ice or a cold drink to them and watch them change to purple right in front of your eyes!  This will happen time and time again, will not fade.  However, it is not recommended that you place these glasses in the dishwasher, or in the microwave as that can damage the image.
