The Hobonichi 5-Year Techo is a Japanese diary that keeps five years of entries in one book. This is a cover made for it, cut to fit the A5 size.

The diary's front and back boards slide into a flap at each end, so the cover holds it shut and lifts off again whenever you want to change it.

Why people love it
• A pen hook on the inside edge holds a pen by its clip, so you never open the diary without something to write with
• It takes five years of scuffs and bag knocks instead of the book taking them
• The tanned leather darkens and softens the more you handle it

Materials run from cowhide leather to cotton and printed fabric, with the designs shown above.
