What I recieved does do fit a Hobbico iron. What I received is only remotely resembles an iron sock but it is basically a cloth bag that is completely sewn shut. It isn't even close to the correct shape for the iron. The hanger 9 tag says "Mechanical Liquid and Chemical Parts. Rolled Header Card. The sticker on the other side says HAN141 Sealing iron sock.Do not buy these unless you somehow verify you are getting the correct part.
