Krosno Poland blue glass controlled bubble vase bottle

Beautiful piece of glass from Krosno of Poland. I believe this originally came with a glass to put on top as a bedside water bottle, but the glass is now missing. It would make a fantastic vase. Cobalt blue glass with clear bottom and controlled bubble in the heavy base. Measures 7.5" tall. Has a few stray marks but no major defects noted. Original sticker is at the top. Smoke- and pet-free home.
