Used Mitsubishi Fude Pen Kit, likely KFK501. Ink appears to flow, but the fine brush tip may be difficult to use. Please consider purchasing if you are interested. Please understand that this is a personally stored item. There is aging, dust, and dirt. I have done a simple cleaning with a dry cloth, but there may be dust and dirt that I couldn't remove. It might be a good deal for those who don't mind. I plan to pack it with vinyl/bubble wrap/paper (all possibly reused) and ship it in a homemade envelope/box. I may secure the contents inside the box and fill it with cushioning material/paper. I will take great care, but as there is basically only one item, I cannot be responsible for damage during shipping. Thank you for your understanding. Please note that this item is only listed on Mercari. If you are interested, please search for the product name on Mercari. I generally do not offer price reductions. Other points to understand are the same as for other products. Thank you. Management Number 01-5026 #MitsubishiPencil
