This listing is for a vintage IBM "Easystrike" Lift-Off Tape Cassette. Was just sitting with a bunch of other older office supplies stuff. Stamp on the box says use prior to 3/9/90. I would imagine it's still usable, but I would just consider this a collectible if you are into vintage items. I understand Lexmark took over, but these were before their time. Reorder number is 1337765.I'm making the total very low ($3.00 + $2.00 shipping). If you have questions or want more pictures let me know.
