Tombow BR-BW Ballpoint Pen Refills Red, 5 pieces, Fine point These are clearance items due to a stationery store's inventory change. The backing card has some discoloration due to age. I tested one of the same product and it wrote without any problems. All items are unopened, but if you wish, please comment before purchasing and I will open one to test it. I will then sell the ones that write properly. I hope someone can make good use of these. Thank you.
