My favorite gel multi pen of all time is the Hi-Tec-C Coleto, and I still have a long-discontinued matte-black Coleto Lumio (since replaced by the Coleto 1000 series) that remains always at the ready in my pen case. The Hi-Tec-C gel pen series is famous for its needle-tip in .3mm, .4mm, and .5mm sizes, and people love the Coletos because they come in a wide range of colors and the refills tend to be less finicky than the standard Hi-Tec-C Cartridge. I can regularly use a Coleto refill all the way to the end of its life without the pen drying or clogging up, probably because they hold less ink (with less opportunities to develop problems over time).
As of this morning, we’re happy to offer Pilot Hi-Tec-C Coleto Multi Pens in three different variations, priced from $3 to $15. Note that the pens are sold without refills - you can customize this pen by selecting from the nearly three dozen different refill possibilities, including mechanical pencils and eraser units, and we’ve spent a considerable amount of time assembling some assortment packs so that you can test all the different refill colors before deciding how and whether to stock up. Options include standard colors, fluorescent colors, pastels, and metallic gels. Happy shopping!
