SOLD!
Four, vintage, glass tube flower holders or vials. They are 4-1/2″ long, and flare at the top to fit in a holder. The body is about 1″ in diameter and the top at the flare is 1-1/2″ in diameter. The bottoms are rounded, so WILL NOT stand on their own. There are some air bubbles and a few manufacturing scuffs. I believe they were made in Taiwan in the 1980s.
These are the replacement tubes for the wood centerpiece bud vase holder or hydroponic system I also have available, but can be used with anything that will accommodate that size tube.
