Thank you for viewing. This is a ball pitching machine that requires no power. The advantage of not needing power is that it's quiet. Electric ones make a loud noise when launching, so you have to be very particular about the place and time you use them, but this one is convenient in that regard. I've used it about 10 times in total. There are signs of use, scratches, and dirt. There are also marks from a white Uni Posca pen used as assembly guides. Please check the photos for the condition. The instruction manual was quite torn from the time of purchase. Please check the condition in the photos. Additional ball loading rails are sold separately by Field Force for 550 yen (excluding shipping), so you can easily increase the number of rails. The nuts in photos 8 and 11 are non-genuine hand-tightened types. I've also included the original spanner and nuts, so please use whichever you prefer. Please note that balls are not included. Thank you for your consideration.
