Query: THIS IS NOT GREEN GAS

DO NOT BUY THIS IF YOU'RE LOOKING FOR GREEN GAS.First off, the product I received does NOT look what the picture shows. The bottle appears to have a wrap around paper label covering whatever it is.Second, the bottle says compressed air. NO WHERE ON THE BOTTLE DOES IT EXPLICITLY SAY THAT IT CONTAINS PROPANE. GREEN GAS IS PROPANE. THIS PRODUCT DOES NOT APPEAR TO CONTAIN PROPANE.I AM *VERY* DISAPPOINTED. IN 10 YEARS OF AMAZON PATRONAGE, THIS IS MY FIRST NEGATIVE PURCHASE.
