This is a tool suitable for indoor swing practice due to its short length. - Golf Planner Shortened Iron Length: approx. 67cm, Weight: approx. 395g - TABATA Tornado Stick Short/Hard Type Length: approx. 67cm, Weight: approx. 300g The shaft is flexible. - DAIYA swing trainer Length: approx. 71cm, Weight: approx. 585g This is an older model, so it doesn't make a "click" sound. There are minor stains and scratches, but I think it can be used without any problems. However, the grip of the DAIYA swing trainer has some discoloration due to aging. Thank you very much.
