Isla Mujeres Shot Glass. A Tall Style. A Mexican island in Caribbean Sea. Clay with a glazed upper and inner. An adorable colorful Roundbottom 3D Couple. Actual Shot Glass is about 4 1/4 inches tall and about 2 inches in diameter at rim. I find no markings on the Bottom of the Glass, just the remenents of the paper sticker. No Chips or Cracks. Please see pictures.
