This hand bound booklet is made of fine rice paper in a traditional Chinese bookbinding technique. It is mainly used for seal imprints and may also be used as a artist notebook or sketchbook.  I use it to show my seal engraving art album as you can see in this YouTube video(8:11).
The booklet size is 5"x 7-7/8" (12.5cm x 20cm) with 25 double-fold leaves or 50 pages.
There are two styles for you to choose from*:
 
Plain Rice Paper - there is no pre-printed border lines. You may use it for whatever purposes such as seal imprint collection, sketchbook,  or guestbook;

* They are both made of fine rice paper.
