This is an INSIDE OUT BAT training bat made by FIELD FORCE, which handles a lot of baseball training equipment. This bat is a training bat for mastering the inside-out swing (the ideal swing path when swinging a bat in baseball). For more information, search "inside out bat" on YouTube, etc., and you'll find plenty of results. Great for your child's baseball practice! Approximately 82cm long. Grip shows signs of use (see photos). I bought it about 4 years ago and have been using it little by little. Please refrain from purchasing if you are sensitive to used items. Price reduction is negotiable. Thank you for looking.
