Hello all. I'm new here. My husband and I recently purchased 2 estate sales. We have been having fun looking up some items. However, this one has us stumped. There is a bin of blue and green glass bottles. We can't find any matches online. Not sure if it's just a bottle or serves another purpose because it looks almost like the top plugs into something.
Pretty sure that's the stopper from a Downy fabric softener promotional bottle (FREE Vase), missing its cork: https://www.worthpoint.com/worthopedia/downy-peacock-blue-glass-genie-bottle-1886671718 ~Cheryl
