Office Depot® 品牌 Callisto 按壓式凝膠墨水筆，中筆尖，0.7 毫米，筆桿多色，墨水多色，50 支裝

Fifty pens for this price is ridiculous value, and the 0.7 mm gel ink lays down smooth, dark lines without any skipping. I’ve been using them for a week of heavy note-taking and the medium point feels just right.

The rubber grip on these pens is a lifesaver during long study sessions, and the 0.7 mm tip glides smoothly without skipping. I've been using them for a month now, and the ink hasn't smudged once.

Got through almost a whole semester of note-taking and the textured rubber grip still feels as good as day one. The assorted ink colors keep things fun, though at 50 pens I’m probably set for a few years.
