This is a PORTER pen case! I bought it, but I've been using a different pen case, so it's in excellent condition with almost no signs of use. The size is 13cm long, 8cm wide, and 5cm high. Please use this as a reference, as these are personal measurements. I think you can store more than the actual dimensions suggest, so please consider that. It will be shipped via Nekopos (anonymous delivery)! #PORTER #Yoshida Kaban #PenCase #PencilCase
