Double-opening clip / clip

Double-opening clip
Double-opening clip

Clips. Ordinary clips have only one opening. It cannot separate the clamped things into different parts. 
When you extract a piece of paper from a pile of clamped paper, it may get a mess.

This double-opening clip can be used to clamp stuff in both sides, one side the paper that frequently used,
and the other side for lesser used paper. Each opening can be opened individually
It can be used to clamp bills, notes or books etc. It’s very convenient.
