Book-Marker / Stationery

BOOK-MARKER is both a bookmark and a pen.

As we usually get a pen to make some marks while reading,and when
we need a pause,we may use the pen as a bookmark.But the pen
often makes the book out of shape and unconvenient to carry with.
On the other hand,the bookmark is actually unoccupied while reading.

Book-marker well combines the bookmark and the pen.
It makes it more convenient to read a book and stop to move.
At the same time,it reduces the use of plastic in produce pens.
