The uni-ball Jetstream RT is a retractable ballpoint pen renowned for its exceptional writing performance, recognized as Wirecutter's Top Pick since 2013. This Costco pack includes 12 pens with bold 1.0mm tips and black ink, offering a smooth, consistent writing experience suitable for everyday professional and personal use.

The Jetstream features uni Super Ink technology, which settles ink particles deep into paper fibers for superior resistance to water, fading, and check washing or document fraud. The hybrid ink formula combines the vivid, smooth feel of a gel pen with the quick-drying, smudge-resistant properties of a traditional ballpoint, making it ideal for both left- and right-handed writers. An embossed rubber grip provides comfort and control during extended writing sessions, while the retractable mechanism keeps the tip protected in pockets and bags. Stainless steel accents add durability and a professional look.
