This is an official game ball approved by the Japan Lacrosse Association, suitable for lacrosse practice. It is the official ball of the Premier Lacrosse League (PLL), a professional league in the United States, and is SEI certified. The ball is made with a blend of 18 materials based on natural rubber to enhance grip. It can be used with confidence for daily lacrosse practice. Recently, lacrosse balls are increasingly used for massage and yoga. This product can also be used for massage and yoga. It is especially recommended for fascia release, particularly for the shoulders and the back of the thighs. Unlike tennis balls, this ball is not hollow and has a certain hardness, making it a popular choice for people with larger builds. It is also popular as a toy for cats and for juggling. This product is brand new and unused. It will be shipped anonymously via Yu-Yu Mercari. Basically, I am not considering price reductions, so please keep that in mind. Prices are subject to change without notice. Please understand. I also have products in different colors and quantities.
