Using this SH Figuarts medical machine is easy. First, take your Dragon Ball SH Figuarts figure, especially the SH Figuarts Son Goku if you have it. Place the figure inside the machine. You can use the optional facial parts to customize the look according to Son Goku's time in the chamber. Turn on the LEDs to see the cool bubble effect. When it comes to maintenance, keep it in a dry place away from direct sunlight. Don't use any harsh chemicals to clean it. Just use a soft cloth to wipe it gently if it gets dirty. And be careful not to drop it as it might break. Enjoy your amazing medical machine!
