Thank you for viewing! I am selling this item to organize my collection and to get out of a financial bind. It is the YSTUDIO THE WEIGHT OF WORLDS. I think it's rare because I don't often see it sold on Mercari or in stationery stores. I used it a little, so the brass parts seem to have aged slightly, but the wooden parts have not aged. Also, I stored it with rolled-up newspaper inside to prevent mold. Since it has been stored at home, there is some dirt on the brass at the bottom of the box, so please purchase only if you are satisfied with the photos and this description. Please feel free to negotiate the price. We do not accept cancellations after a successful bid, exceeding the payment deadline, or returns due to customer circumstances. We will accept price reductions. I bought it because it looked cool, but I only used it for a test write and then stored it, so it hasn't aged in the way brass typically does. The main body is in beautiful condition because I stored it carefully, but there are small scratches on several parts of the pen and the box due to home storage. Please purchase only if you are satisfied with the photos. Please feel free to negotiate the price.
