Includes two unused gas cylinders! Plus, I'll include one more (with a small amount remaining). I bought this for work about 5 years ago and used it for about six months. I've kept it in storage since then. - Operation confirmed - Cleaned, but there are some fine scratches and dirt, especially inside. Overall, it's in good condition. - Box and instruction manual included, but they are slightly damaged. ● Please note that I am unable to negotiate on the price.
