This is a touch-panel multi-effects unit, powered by a battery. Built-in battery types are not very common, but having one less power supply makes it much easier to handle. I used it in the studio for two hours, and the battery only drained about a quarter. A film is applied to the touch panel. The switch hat and effects board are not included. The unit itself is included (all accessories are complete). I purchased it new from Soundhouse (new price: 72,600 yen) and have only used it for about a month, so it's in good condition, but please understand that it is a used item.
