Hair Clip Pen

Saw this at a pasar malam (night market). And why would this be a good idea? Undo your hair to write something???

Here's another clip pen. You press one end for the pen nib to come out. You then press the clip handles to retract. But wouldn't that simply release everything under the clip?

I guess this would be rather useful in the end. A pen that holds stuff and at the same time provide a writing instrument!

Quite useful with a clipboard, even as an auxiliary clip.
