Ruột bút gel đen 0.7mm | Bộ 2 cây

Everyday note-taking and the ink stays a deep, true black from the first stroke to the last. The 0.7 tip glides without skipping, and it’s nice to have a spare ready when the first one runs dry.

The 0.7 mm tip writes exactly the line width I need for quick notes, and this ink is genuinely rich and dark—no skipping or fading mid-sentence. Swapped both refills into my everyday pens and they glide just as smoothly as the originals.

Swapped the refill in my go-to pen this morning and the 0.7mm tip writes smooth and dark right out of the box. The ink flows consistently without any skips on my grocery list, and two in the set means I’m set for months. Exactly what I needed.
