The Pica 991/054 VISOR Luminescent Permanent Marker Refill, Fluo-Orange (4-Pack) is a replacement refill set for the Pica VISOR permanent marker system. This is a permanent marker refill designed for replacing worn or spent marker inserts when you need bright, durable marks on common jobsite and shop materials. Model Number: 991/054.

What matters here is visibility and convenience. The fluorescent orange ink color is built to stand out better than a standard dark mark in many layout, sorting, and identification tasks. If you are marking parts, tagging cut points, or making temporary visual callouts, a bright refill can save time because marks are easier to find at a glance.

This refill is intended for multi-surface use. Source data lists paper, cardboard, some plastics, and some metals as recommended surfaces, which makes it useful for contractors, shop workers, warehouse users, and serious DIYers who move between packaging, materials, and fabricated parts instead of working on just one surface type all day.

The refill uses alcohol-based permanent ink and is listed as water resistant. In practical terms, that means the mark is meant to hold up better than a basic dry mark when the work area is exposed to light moisture or handling. That makes more sense for labeling and general identification work where you need the mark to stay put after application.

The line size is listed at 0.7 millimeters with a chisel point style. That gives you a fine enough mark for controlled writing and detail work, while the chisel-style tip can still help with legibility and line definition depending on how you hold the marker. For users who care about clean, readable marks more than broad paint-marker coverage, that is the right lane for this refill.

This is not a standalone marker. It is a refill pack, which is the main buying decision here. If you already use the Pica VISOR permanent marker and want to keep it working with the same bright fluo-orange output, this pack is the straightforward replacement. It is best suited for anyone who already knows the VISOR platform and wants quick, clean restocking without switching marker systems.
