Today it's a cool old seltzer bottle.
These were popular in the 1950-1960's for the home bar.
This one dates to that time period with it's "mesh mail" steel wrapper!
Not sure where this one is made, probably in Western Europe.
Just add a CO2 Cartridge and you have sparkling water for your next cocktail. These worked then and will work today. It's Vintage Gear for Guys!
