Used Montblanc genuine converter. The old genuine model is currently unavailable for purchase new and is becoming increasingly rare, making it a valuable item. We have a large stock, so bulk purchases are possible. If you wish to purchase in bulk, please state the desired number of pieces in the comments. For bulk purchases, we will discount 100 yen per piece. No further discounts are available. We will ship after confirming the operation and cleaning the converter. Montblanc converters are broadly divided into two types: old and current models. The current model is also listed separately. We cannot answer questions about which converter (old or new) is compatible with a particular pen. The box shown in the image is for photography purposes only and is not included. This listing is for the converter only. We will clean it as much as possible, but please be aware that there may be some rust or ink stains that cannot be removed.
