Why do dark spots appear on the surface of the leather cover?

They are natural marks that occur during the tanning and dyeing process of natural leather when components in the material react with iron in the air.

When you unpack the product and take it out, scattered dark spots on the leather surface may catch your eye first. Hobonichi leather covers are made from natural leather without heavy surface processing. In addition to wrinkles, blood vessel marks, and fine scratches remaining on the raw material, black dot-like spots can also form during tanning and dyeing as leather components react with iron in the air.

This is a cover dedicated to Hobonichi 5-Year Techo, made of cowhide on the outside and cowhide and polyester on the inside. With a red bookmark and a hook for a pen clip, it is convenient for keeping the diary and writing instruments together. Illustrations and a map from the original Moomin novels are engraved on the cover and inner pocket, making it suitable to keep in a drawer or on a desk for a long time.

Why does the lining or outer stitching appear loose or puckered when the Techo cover is opened flat to 180 degrees?

Because of the structural characteristic designed to allow the Techo cover to open completely flat to 180 degrees on a surface, the outer seam or lining material may appear somewhat loose or lifted.

The moment you place the planner on a desk and open it completely to both sides, it immediately catches your eye right at the inner fold. This is a natural phenomenon. Hobonichi's Techo covers are structured to open flat to 180 degrees on a surface, so the outer stitching area may pucker or the lining material may look loose.

How do you use the small pen hook inside the 5-Year Techo cover?

It is not designed to slide the entire pen body through, but is a loop conceived to hook the pen's clip into the opening.

It has a diameter of 8mm. This means it is too narrow to fit the whole pen body through, so only the writing instrument's clip should be hooked over it.
