ปลายปากกาลูกลื่นทดแทน

My rollerball feels brand new again—the line quality is crisp and consistent, and swapping in the tip took seconds. Honestly, I'd forgotten how smooth a proper inkball can be.

Ink flow has been steady from the first line, and the tip sits snugly in the barrel without any wobble. My notes look crisp again, just like when the pen was new.

My other tips felt scratchy after a few months, but this one glides like the pen is brand new again. The ink flow stayed perfectly consistent through my last two weeks of note-taking, and it took me all of two minutes to swap in.
