The Hobonichi Techo is a Japanese daily planner. This is a slim case that holds the A6 size lying on its side, along with the papers, tickets and pens that pile up around it.

Why people love it

• Soft PVC and only 8 mm thick, about 75 g, so it slips into a bag without taking up room

• Snap buttons hold it shut and the lid folds down with a click, which is where the name comes from: an alettone is the aileron on an aircraft wing

• Clear pockets on both sides, so you can see what you put in

• A pocket on the back keeps a ticket or a memo pad within reach

• A line is pressed into it in gold foil: writing by hand is like sending your mind on a journey

It comes in three quiet colours, shown above.
