Denim water bottle . Blenko Glass.

Mary from Bridgeport sent me a photo of the denim water bottle.  She's correct I MISSED THIS ONE.
If you are a water bottle collector - you'll want to search for this unique color.  

Denim’ is the name for our newest Special Edition Water Bottle.

Made of two distinct gathers or layers of glass, this is our Cobalt glass cased in our experimental Bronze glass.
