I bought this at a general goods store. I thought it was cute and bought it, but I didn't use it, so I'm putting it up for sale. It's thin and produces mixed colors (see photo 6 for a writing test). The shape is hexagonal and thick. Length: 17.5 cm The leather pencil case is sold separately, but I will include it. *Please refrain from price negotiations. Thank you for looking! ^_^
