Notably, the cassette itself, instruction manual, and town map are in very good condition. [Condition Details] Cassette: No noticeable scratches, and the terminal part is clean. Startup has been confirmed on an actual machine. Instruction Manual/Map: Shows little use and is clean. Outer Box: Has scratches, corner wear, and stains due to aging. Please check the photos for detailed condition of the box. Other: Includes a warning leaflet and a dedicated plastic case. [Shipping] As this is a rare collector's item, we will take strict measures against water damage and impact (bubble wrap) and ship it carefully via Mercari delivery. This is a condition that we can confidently recommend to collectors who "prioritize the cleanliness of the contents over the condition of the box." *Please consider this item with the understanding that it is a precision instrument from nearly 30 years ago.
