ローラーボールペン替芯 - 黒インク

Went through a whole notebook with the first refill and it’s still going strong, which I didn’t expect from a 0.5mm tip. The black ink dries fast enough that I haven’t smudged a single page, even when I’m jotting notes left-handed. These two refills are a steal for how long they last.

My old refill was skipping and dragging, but this 0.5mm tip glides like a new pen. The two-pack means I’ve got a spare ready when the first one runs dry, which is perfect for my daily notes.

Ink flows so smoothly with this 0.5mm tip, and it dries fast enough that I don't smudge my notes when I flip pages. Two refills in the pack means I won't be scrambling to reorder for a while.
