I bought these intending to use them for night golf, but I never went, so they're new. 【Product Description】 ・These LED golf balls are perfect for nighttime or early morning practice. ・They use high-elasticity flash balls, achieving the same distance as competition balls. ・The built-in LED reduces the risk of losing track of where your ball went. ・Available in six colors: red, green, blue, white, yellow, and pink. ・They feel the same as regular balls. They are the same size and weight as official balls and look like regular balls when not lit. ・They are highly visible at dusk, during night games, early morning golf, and in smog. ・Recommended for night practice and as prizes for competitions!
