Plastic Margarita Glasses, Hot Tub Plastic Stemware

These are so great for hot tub use or just for outdoor settings. These could be from the late 80’s, I’ve had them for so long I can’t remember & I can’t find another set just like them to compare to. They are used & not in perfect condition, but pretty close to it for their age. Four, blue, stemmed glasses. Three & a quarter inch wide at the base, four & three quarter inch wide across the lip & six & a half inches tall. Cheers! Plastic Margarita Glasses, Hot Tub Plastic Stemware
