Binder Flip Clip

A binder clip that flips, combining a document clamp with a photo or note holder in one piece.

It solves the problem of the note that needs to stay with the stack. A plain binder clip holds paper; this one holds paper and then holds something up in front of it, which is the difference between filing a document and flagging it. Cheap enough for a mailer insert and small enough to sit inside an envelope.
