SSK's 78cm, 570g youth soft-ball bat, SKYBEAT31K RBJ. - Brand: SSK - Model Name: SKYBEAT31K RBJ - Length: 78cm - Weight: 570g Purchased for the NPB Junior Tournament selection. Bought in August and used for 3 months until November. It hasn't been used extensively, so it's still in good condition. Compared to the V-Kong, the V-Kong's metallic sound didn't suit the child, and the SKYBEAT felt better and was preferred. Selling because we are switching to a general soft-ball bat.
