The Green Jangsoo Pen Holder Pocket Notebook is a perpetual pick and one of our all-time favorites! The spiral binding is extremely strong and does not deform easily with use. The cover wears well and is made of recycled paper, protecting the 80 recycled pages from damage. It also features micro-perforated pages for easy and clean removal. We're very lucky to offer such a perfect piece of stationery! SPECIFICATIONS SIZE : 115 *164 *11mm PAGE : 80pages
