Uni-ball Jetstream Retractable Ballpoint Pens, 1.0 mm, Low-Smear Hybrid Ink, Tamper-Resistant, Fast Dry, Smooth Flow, Ideal for School, Office & Home Use, Black – Pack of 12

Model MI-SXN210-BK, hybrid ink, 1.0 mm bold point, fast-drying and low-smear formula, retractable click mechanism, cushioned grip, black ink, pack of 12 pens.

Yes. The fast-setting, low-smear ink helps reduce smudging, which is especially beneficial for left-handed writers who often drag their hand across fresh ink.

Simply click to extend the tip for writing, and click again to retract it when you’re done. The cushioned grip helps maintain a steady, comfortable hold during longer writing tasks.

Jetstream pens are designed to be refilled with compatible ink cartridges. When the ink runs low, replace the cartridge with a 1.0 mm Jetstream refill to restore writing performance.

Ideal for school, office work, home use, labeling, forms, grading, and everyday note-taking where bold, clear lines and quick-dry ink help pages stay neat.

The ink is non-toxic and the pen is designed for regular handling. As with any writing instrument, keep away from very small children to avoid choking hazards from the cap or components.

If you’re considering different line widths, you can compare with these commonly available Jetstream variants on Fepy.com: 0.7 mm option: https://fepy.com/uni-ball-jetstream-0-7mm-retractable-ballpoint-pens-black and 0.5 mm option: https://fepy.com/uni-ball-jetstream-0-5mm-retractable-ballpoint-pens-black. The 1.0 mm option provides bolder lines, while the 0.7 mm and 0.5 mm variants offer finer lines and slightly different ink flow and drying characteristics.

The 1.0 mm tip creates thicker, more pronounced lines—great for headings, labels, and forms that need to stand out. Finer tips like 0.7 mm or 0.5 mm offer more precise writing for dense note-taking, detailed outlines, and small print. Your choice depends on whether you prioritize bold visibility or finer detail.

A 12-pack provides a cost-effective option for classrooms, offices, or households that need reliable, consistently high-visibility writing with quick-dry ink. The Jetstream blend of gel-like smoothness and ballpoint-like dry time, plus the retractable design and cushioned grip, offers a durable, everyday writing solution at a favorable price-per-pen compared with many premium alternatives.

Jetstream ink generally performs well on standard office and notebook papers with minimal bleed-through. For high-opacity results on thicker sheets or for minimizing show-through on double-sided pages, test on a sample sheet or use standard copy paper to maximize readability.

Store pens with the tips retracted to protect the nib and maintain tip integrity. Keep the caps and bodies clean, avoid excessive pressure while writing, and replace ink cartridges when the ink flow noticeably slows to preserve smooth performance.
