Instruction Manual, Case Included Casio Kanji Databank DKW-100 Working Condition Vintage model released in 1991 Battery replaced in July 2025 I think it's in pretty good condition for its age. Although I haven't confirmed all functions, all buttons respond. Please refrain from purchasing if you are a nervous person or if you are looking for perfection, as this is a vintage item.
