A demerit of pencil is that it's a bit harder to store and carry around.
The ever-exposed lead can stain books, notes, bags with graphite and dye and sometimes be dangerous if it's well sharpened. Of course, you can choose something like Faber-Castell Perfect Pencil or put some cap on the lead end to prevent that. Nevertheless pencil case is usually the best solution.
In some countries like Korea, the state of pencil is not so high and the people think it is just for kids or for worthless use. Therefore, it is a bit hard to find some pencil case that is proper enough to be put into a gentleman's briefcase. You can choose some luxurious pen pouches and cases made by some pen makers for collecting pens. However, because of the length of normal pencil is much longer than ordinary pen, it's also very hard to find some appropriate ones.
Generally, eraser-tipped pencils are longer and the length is at most 19.5cm. I usually use 2 or 3 pencils for my work in a day, and it seldom excess 5. Consequently, I needed a for-adult pencil case, which can contain at least 5 graphite pencils, an eraser, a few pens, colored pencils and others.
And I finally found this perfectly appropriate one, COBU leather PENCIL case.
The basic material is cowhide. This almost-rectangular pencil case can be secured with the YKK zipper. A partition divides the inside and it can hold 5 woodcased pencils. The dimension is about 20cm*7cm*3.5cm so you can put almost all kind of pencil including newly sharpened eraser-tipped one, except some curiously long pencils like LYRA Orlow Cellugraph 1174.
You can stock about at most 8 to 10 pens and pencils in lower space.
This pencil case is packaged in a simple and nice paper box. The face of sewing rabbit (probably it's leather piece?) is quite cute. COBU seems a Japanese minor enterprise. The price of their product is not cheap, but I think they're using really quality material so that it's not overpriced.
Only black colored model is available in Korea, but you can find pink, red and deep blue colored model in Japan. You can also buy another models there those are secured by magnetics, not zippers.
When it's closed, every single side of this rectangular pencil case is so simple and neat. The finish is almost perfect.
The COBU leather pencil case always places in my briefcase. Pencils inside it replaces by other ones everyday, but I will hardly find another pencil case that can replace it.
