Thank you for viewing! This product is a Makiwara for training your fists! The item in the image is a sample. Changes to the length are possible! You can also widen the gap between the base board and the Makiwara board by 5 centimeters, so please message me before purchasing★ You can also widen the width of the straw board and the base board, so please consult with me. It's hard at first, but it will become more flexible and just right as you use it★ The actual product will be made after receiving your order. Use it by placing it on the floor. Use it by tying it to a tree or pillar. Or use it by fixing it to a wall. I have many other items for sale, so I hope you will take a look. Thank you. #Karate #Training #Workout #Dumbbell #MuscleTraining #CoreTraining #Makiwara #Sandbag
