One of the most talked-about products over the past couple of weeks has been the Uniball Jetstream Parker-Style refill, which combines the Jetstream’s hybrid ballpoint-gel ink with a refill format that’s widely compatible with a variety of pens manufactured by third parties, including Retro 51 Rollerballs, the Baron Fig Squire, and many Kickstarter pens. I immediately bought two packs of these refills in .5mm and .38mm sizes and loaded them into my Baron Fig Squires, and am pleased to report that I now have an ultra-fine writing option for one of my favorite retractable rollerballs.
I purchased my refills from the Mitsubishi Pencil Company (which I believe owns the Uni brand) via Amazon. Due to the savings available by purchasing a four-pack, I can’t justify purchasing these refills individually at the price point at which certain retailers are selling them. Relatedly, Uni also sells the refill packaged with its “Jetstream Prime” premium body, and also has a gift pack in which you can purchase the Uniball Jetstream 4&1 multi pen along with refills and a Kuru-Toga Advance mechanical pencil. As of the time of publication of this post, all products were Prime-eligible.
