American Greetings Corporation/Design Ware, Watermelon Fruit Floating Candles 4 per Pack, Lot Of 2, total of 8 candles. The burning time or material is unknown. They measure 1 1/2” x 3/4”. I believe these are nearly vintage. As you can see in the packaging, some green has flaked off. It’s still green under any of the flaking, looks like a true watermelon rind.
