Lacrosse balls. Four used balls. My family used to play and these were left at home after they retired. Some have the school name faintly printed on them. Please be aware of this. They have good elasticity, so they can also be used as massage balls. I think they can also be used for baseball practice or play as baseballs. As you can see in the photos, there are scratches and stains. I washed them, but they didn't come off. These are for people who just want to use them. Please refrain from purchasing if you are looking for new or clean items. I don't go home very often, so please allow up to a week for shipping.
