Pilot Juice Up 0.5mm LP3RF Gel Pen Refills (10-Pack Box)

Extend the operational life of your favorite Pilot writing gear with factory-authentic Pilot Juice Up LP3RF-12S5 gel ink refills. Engineered in Japan, this 0.5 mm extra-fine refill incorporates Pilot's proprietary Synergy Tip (ST)—a dual-structure nib fusing the sturdiness of a conical ballpoint with the ultra-smooth ink channel of a pipe needle tip. Loaded with premium water-resistant pigment gel ink, the LP3RF-12S5 offers richer line density and effortless glide across standard notebook and copy papers without feathering or bleed-through, delivering dependable, clean handwriting for office documentation, legal paperwork, and expressive journaling.

Frequently Asked Questions

What is the difference between the LP3RF-12S5 and LP3RF-12S4 refills?

The LP3RF-12S5 features a 0.5 mm ball diameter, offering a slightly bolder line and silkier gliding feel compared to the ultra-fine 0.4 mm LP3RF-12S4, while sharing identical barrel dimensions and pen compatibility.

Will these 0.5mm refills fit in a pen body originally sold as 0.4mm or 0.3mm?

Yes, all Pilot Juice Up retractable pen bodies utilize the exact same internal cartridge casing, so 0.3 mm, 0.4 mm, and 0.5 mm refills can be freely swapped.

How should uninstalled refills be stored?

Keep them in their original sealed packets at room temperature away from direct sunlight. Do not remove the red protective wax seal on the tip until you are ready to insert the refill.

What is the store's customer support and return policy?
