Thank you for looking! This product is a makiwara for training your fists! The item in the image is a sample. Length changes are possible! We can also widen the gap between the base board and the makiwara board by 5 cm, so please message us before purchasing ★ It is also possible to widen the width of the straw board and the base board, so please consult with us. It will be stiff at first, but it will develop a good flexibility 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 post. Or use it by fixing it to a wall. We have many other items for sale, so please take a look. Thank you very much. #Karate #Training #Workout #Dumbbell #MuscleTraining #CoreTraining #Makiwara #Sandbag
