G2 墨水筆芯 適用於加重旋轉筆

The two-tone set (blue and black) covers me for both my oil slick and black pens, so I’m stocked for months. The ink flow is smooth and consistent right out of the box, no skipping or scratching on the first try.

I was dreading having to buy a whole new pen just because the ink ran out, so finding these refills that work with both my black and the oil slick version was a relief. The black refill has been keeping up with my daily note-taking without any skipping, and having the blue on hand for edits is a nic

The blue refills write just as smoothly as the black ones, and the ink seems to last a decent while before running dry. I ordered the pack for my spinner pen and both colors are working perfectly, no skips or smudges so far.
