This is a Staedtler 15cm ruler. I've only used it a few times, but there are marks on the plastic case. Please check the photos for the condition. Please understand that this is a used item. I used it for drafting, but I no longer need it, so I hope someone who can use it will find it useful! ● I also have other drafting supplies for sale, so please take a look if you'd like ♡₊⁺ #Staedtler #Drafting #DraftingSupplies #Architecture
