Thanks to years working at Hallmark, I am a loyal user of 3x5s for notes, reminders and various writing needs. The 3×5 has a long history at Hallmark including the infamous “When you care enough to send the very best” having originally been jotted down on a ubiquitous 3×5 before being immortalized on the back of greeting cards everywhere.

Needless to say, finding this durable metal box with vintage metal-topped dividers was quite the coup. (by me)
