TWSBI Classic fountain pens are now available at our online store! These are beautifully made piston filler mechanism precision pens that you can service on your own. Each pen comes with a part removal wrench tool so that you can take them apart and put them back together. Perfect for those OCD users or really clean freaks amongst us who still love changing out the endless bottles of ink colours you have collected. 🤣 well, you can do better, just buy more pens! 5 different colours to choose from, black, sapphire, burgundy, turquoise and white. Oh, choose a free 90 ml bottle of Monteverde ink while you are at it, only while the promotion lasts!
