The $2 daiso china pen (version 1: not the current version)

no, I am not talking about the rivere pen. yes, that's good, but the body cracks too easily, and the window for imagination is quite small.

It's this pen I am talking about , in grey and white. the brushed metal edition is my doing. again. i never expected this pen to be so full of surprises, so here goes.

 the nibs are even more astonishing:
left to right: inner matt nib, outer matt nib, flex nib, normal nib.

 And their cartridges are even more crazy: http://pen-vault-ink-cellar.blogspot.sg/2015/09/a-standard-ink-cartridge-new-twist.html
