Mitsubishi Pencil Uni Jetstream Ballpoint Pen Refill 0.7mm Red SXR8007.15 Mitsubishi Pencil Price: - This is a Jetstream ballpoint pen refill. It comes in a set of 6. I bought these a few years ago, but I haven't been using them lately, so I'm putting them up for sale. They are compatible with multi-function ballpoint pens. Please refer to the manufacturer's list of compatible products: https://www.mpuni.co.jp/products/ballpoint_pens/refill_jet.html Also, although they are unused and unopened, they have been stored at home for many years, so please consider purchasing them if you don't mind. Shipping will be done by waterproofing them in a clear bag, etc., and then shipping them via Yu-Packet Post Mini. #Mitsubishi Pencil #Mitsubishi Pencil Uni Jetstream Ballpoint Pen Refill 0.7mm Red SXR8007.15
