Handmade Metal Pen Holders Saji Shaft: ¥578 Round Shaft Twin Shaft: ¥1036 Subtotal: ¥1614 + Shipping: ¥198 = Total: ¥1812 Delivery: 5-7 days ★ For use with Zebra round pen nibs We have confirmed operation for over six months with Zebra nibs. Since Zebra nibs are slightly larger in diameter than those of Tachikawa and Nikko, you can use them by widening the hole yourself with a screwdriver or pliers. After expanding the diameter with the above work, there is a possibility of wobbling when attaching Nikko or Tachikawa nibs, so it seems to be fine if you use it exclusively for Zebra nibs. ※ These are items that were initially made by a amateur for myself and my family, and are being sold at cost. Please do not expect the same level of precision as industrial products.
