SkyOx SK12-24 24 cu.ft O2 tank w/ regulator and 2 place manifold. Also throwing in the padded carrying case and 5 Oxymizer cannulas. I bought this in 2015 or 2016 and have used it a handful of times. Works great and never had an issue with it. Tank is currently at ~1300lbs and has not been used for about 2 years (my 22T has built-in O2, this got forgotten in a closet...)

****The tank is dated 2015 and is aluminum. It is VERY LIKELY due for a hydrostatic testing before it can be refilled!!!****

Not super keen on shipping it due to it being a charged O2 canister, so please be located in CA/NV, or have a plan on how to pick this up.
