This is a used Montblanc genuine converter. The old genuine converters are no longer available new and are becoming increasingly rare, making them valuable. We have a large stock, so bulk purchases are possible. If you wish to purchase in bulk, please state the desired number of converters in the comments. For bulk purchases, we will discount 100 yen per converter. No further discounts are possible. We will ship after confirming the operation and performing a simple cleaning. 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 them as much as possible, but please be aware that there may be some rust or ink stains that cannot be removed.
