This was interesting so we picked it up. It?s point of sale advertising for hp ExpertOne. This magic cube opens up to reveal ???? We don?t know because it?s still sealed in plastic. Any computer or technology collector might want this for a collection as well as any current or retired Hewlett Packard employee. Perhaps someone out there worked (or works) on ExpertOne. We bought several of these from different companies in different industries. We were told the original owner had an advertising premiums business so these were either samples or leftovers from past buyers. This is the smallest ?Magic Cube? we found. It is 2 inches cubed. Will ship USPS with tracking to winning buyer
