New, Unused, Unopened MUJI Smooth Gel Ink Ballpoint Pen Refill 0.5mm Brown 10 pieces I purchased these for my home stock, but I haven't had much opportunity to use them, so I'm putting them up for sale. ☺︎ This color is currently discontinued, so I don't think it's available in stores! If you're looking for these, please consider purchasing them. Although they are new, unused, and unopened, please purchase only if you don't mind that they have been stored at home. No price reduction.
