reduced preSsure pEn

This is named as reduced pressure pen.i had no idea why it has such a weird name.How does it function as pressure reducerMaybe the supplier wanna increase the sales of this product,so think of naming it like that lol...

The body of the pen is real long.And it can bend up or down.Nowadays,pen acting not like a pen.The appearance of it,really,none will expect, it is a pen.Ha-ha...@_@ i like using peculiar pen.Some have thin body while some are thick.
