Texas Instruments Calculator-Based Ranger CBR Accessory Dirty Box‎ With Cord New

Found in my grandmothers garage. Looks like the box had some water damage. The items are not affected. They are brand new and never used. But the box has had it. It's gross and dirty. Full disclosure. There's no calculator with this set. It's just an accessory to a calculator. This is a vintage items from 1997
