This is a set of three black Sharpie permanent markers from the US. Length: 13.7cm In the US, you can just say "Bring me a Sharpie!" and people will know what you mean. It's similar to the "Mackee" or "My Name" markers in Japan. I purchased these about three years ago. Other pens I bought at the same time, which I have opened, are still working fine. These are unused, so I have never opened the caps. If you would like me to test them before shipping, please let me know in the comments. These are unused, but they have been stored at home by a private seller. Please understand this before purchasing. I will use recycled materials for packaging.
