These are hand made clear blown bottles I made several years ago. This is not a set. Each one is a little different. They hold roughly 15 ml of fluid. Made from clear COE 90 glass. The can be used for what ever you want. Holding medicine or perfume or scented oils. Past customers have used them to put sea glass and small shells. They can also work for magic potions ans steampunk alchemy bottles They stand around 1 and 1/2 inches tall. With may very depending on the bottle. I can make more. I hope you enjoy them. I can also make sets upon request. This is not currently a set. One bottle per unit sold.
