Brand New, originally purposed for emergency oxygen…two in a hard case.
These actually came out in 1987 so I would not recommend using them for medical or health.
They may be good for having the bottles re certified at a welding store and filled with CO2 for kegging. I can see them being part of a mobile kegging system or in the brew kitchen. Have gauges, adjustable valves
11 x 4.5 inches each
