SHOT COLLAR Bat Weight Baseball Hardball Junior High School Hardball High School Baseball Practice Swing This is a bat weight. Many professional baseball players use it. Unused with tags. It can be used for hardball metal bats, as well as wooden bats. There may be some minor scratches and scuffs from the time of purchase. There may be some errors as it is a personal measurement. Personally, I think it is in good condition, but it has been in someone's hands once, and some buyers are very sensitive, so I will consider the condition of the product to be "like new". Please check the photos. Please refrain from purchasing if you are overly concerned about scratches or other imperfections. Shipping will be via Yamato using recycled cardboard. Thank you.
