Delfonics has been the local standard in Japan for brilliant, and innovative stationery for over 20 years. Almost never seen outside of Japan, the Walker Shop is very honored to carry this highly-coveted stationery product. Rollbahn notebooks feature perforated cream-colored interior pages with pale grey dotted grid lines (it is graph paper, but the graph lines are very subtle dotted lines). Each notebook has 5 full-size clear plastic pockets in the back.
