Training baseboard is being used for tennis line training. And it can be loaded with water sand, easy to pour, light and durable. This training base board is being sold as a replacement if you already have an old worn out training base. We recommend fill water and sand together to prevent the base from moving, give you enough stable. Easy to use and convenient for training without picking the ball and it’s helpful for single person practice. Also it could improve your concentration, athletic ability and hand and eye coordination, and develop interests of sports.
The rubber plug should be pulled out, where you will be putting the water or sand, the small hole is where you will tie the line of the ball that you will be using. You can also check our Training ball set & Racket bandage. Enjoy your shopping at Kitseek!
