Revised training text for the sale of Type 2 products. - Title: Type 2 Sales Training Text, 4th Revised Edition - Publisher: High Pressure Gas Safety Institute I purchased this to obtain a qualification, but I am selling it now as I no longer need it. I used it for studying, so there are some signs of wear and tear. Please purchase only if you are not concerned about this. The list price was around 2,500 yen, but since this is an older revised edition than the currently sold version, I am selling it at this price. Thank you.
