ชุดแปลงปากกาหมึกซึม TornadoTM เป็นปากกาลูกลื่น

The swap tool in the kit made converting the feed assembly a five-minute job, and the capped rollerball tip writes with a smooth, consistent line that feels completely different from the fountain nib. Now I’ve got two writing styles in one pen body without buying a whole new pen.

Swapped the feed assembly in about two minutes and it fits perfectly snug—no wobble at all. The rollerball tip glides way smoother than I expected for a converter, honestly feels like a brand new pen.

I’m not the handiest person with pen parts, but snapping in the rollerball tip took me under five minutes and it fits snugly inside the barrel. Now my favorite pen glides like a gel pen instead of needing ink refills, which is exactly what I wanted from this swap.
