Used – Excellent / New old stock appearance
Card is still in the original clear blister. Box has light shelf wear, scuffs, and some paper residue on the front artwork (see photos). Card face looks clean. Backup battery is original and almost certainly expired after 30+ years — treat as untested for data retention.
