I was using this until recently. The main unit is scratched and dirty. Please check the photos for details. The main unit has been initialized. There are no problems with the operation itself. All the accessories shown in the photos are included. The Strike Spacer, IC cards, etc. shown in the 6th photo are all unused. The battery is a used item, but I will include it as is.
