Thank you for viewing! This is a limited edition ink made to commemorate the 90th anniversary of MONTBLANC's Meisterstück. I used it to fill a pen two or three times, but it has been stored at home ever since. I purchased it over 10 years ago. It is a permanent ink and becomes water-resistant when dry, but as it is old ink, please use it at your own discretion. The bottle label is cute (*^^*) - Brand: Montblanc / MONTBLANC - Color: Permanent Grey / Permanent Grey - Capacity: 35 ml If you have no questions, you can buy it immediately! I will ship it via Rakuraku Mercari's Takkyubin service☆ Thank you very much m(*_ _)m #Montblanc #MONTBLANC #FountainPen #Ink #LimitedEditionInk #PermanentInk #ClassicInk #Meisterstück #WaterproofInk
