This item was used during my student days. I've kept it in its case for a long time, but I'm selling it because I no longer use it. I purchased it from Lemon Gasui in Ochanomizu. I think it's relatively clean, but please understand that it's old. There are marks where a name was written on the case and erased. I'm sorry, but I don't know if the included drafting tape is still usable. Please purchase with the understanding that this is a used item. Thank you. #DraftingBoard
