This is a short 84cm knock bat. It has only been used 2-3 times, so the hitting surface is relatively clean. I bought it new before this summer, and after use, I wiped it down and stored it indoors, so I don't think there's any concern about moisture. - Brand: ZETT - Type: Knock Bat - Color: Red - Compatible balls: Hardball/Softball, both - Size: Length 84cm, Weight 530g As it is a knock bat, there are some scratches on the tip. In terms of size, I think it's an easy-to-handle size for use in youth baseball, junior high school baseball, and recreational baseball. Stored in a non-smoking/no-pet environment.
