PenKer / pen


This is not a ordinary pen
It's "PenKer".
When we use a pen to mark book pages, Pen will be easy to fall off from the book, and one side of the book will be bulged out. So, carrg the book with pen inside around will be hard.
Unique Feature of "PenKer", which is Spreadibility of layers in pen, will release us from unportabiblity.
