This is my ruler. It's 20cm long. I bought it because I thought it was cute, but I haven't used it, so I'm putting it up for sale. It seems to say that it's recommended for ages 4 and up because the tip is sharp. I've stored it in this condition, so I selected "no noticeable scratches or stains." I'm keeping it at home, so I'm looking forward to purchases from those who understand. Thank you.
