Now I don’t read Japanese, so was a bit puzzled by the large instruction sheet and detailed diagrams. Also the grip is rather unusual in that it has a rib running around it. It all came together when I found out that the pencils name, “Otehon”, translates to “Example”, and that this pencil is intended to help correct (little) folk who hold their pencil incorrectly, hence all the diagrams and instructions. The rib around the lower part of the grip is to help with correct finger positioning.
It also comes with blank little name-tag stickers that go on a flat spot moulded at the top of the pencil. Help keep those annoying classmates from snaffling your pencil.
I normally associate Sailor with expensive prestigious fountain pens, so a basic lightweight pencil was quite a change.
