Frequently Asked Questions

Which pens are compatible with the Pilot LP3RF-12S4 refill?

These refills are the direct original replacement for Pilot Juice Up gel pens (including LJP-20S4, LJP-20S3, and LJP-20S5 bodies), and also fit several standard Pilot retractable gel pen models with matching barrel lengths.

How do these refills protect against drying out before use?

Each individual refill is factory-sealed inside a moisture-barrier pouch and features a protective silicone wax tip seal that you remove just before installing into your pen.

Can I use a 0.4mm refill in a pen that originally came with a 0.5mm tip?

Yes, Pilot Juice Up pen barrels share identical internal dimensions across 0.3 mm, 0.4 mm, and 0.5 mm variants, allowing complete interchangeability between tip sizes.
