Mitsubishi Gel Ink Ballpoint Pen Refills Uni-ball Signo UMR-10 Refills 1.0mm For two boxes, a total of 20 pieces New, unopened. I will sell these to those who understand that they are stored at home. Please refrain from purchasing if you are sensitive to such things. Please note that there may be oversights due to my amateur inspection. I will take the refills out of the boxes and put them in a Yu-Packet Post Mini envelope, and the boxes will be flattened and folded to be included. Please consider purchasing only if you agree to this. #Mitsubishi #Gel Ink Ballpoint Pen #Refills #Uni-ball #Signo #UMR-10 #Refills #1.0mm
