The Pica 991/44 VISOR Luminescent Permanent Marker Refill, Yellow (4-Pack) is a refill pack for the Pica VISOR permanent marker system. This is a permanent marker refill designed for replacing worn marking inserts in a compatible industrial marker used on dry and wet surfaces. Model Number: 991/44. If you already use the VISOR marker body, this pack keeps you working without buying another complete marker.

What matters here is simple: this is a maintenance item for people who actually use their markers. Instead of tossing the whole marker when the tip is spent, you swap in a new refill and keep going. That saves waste, keeps a familiar marker in service, and makes more sense for contractors, shop users, and tradespeople who burn through marking supplies.

The yellow luminescent color is meant for high-visibility marking, which is useful when you need lines that stand out better than standard dark marks on certain materials. Product data also identifies this as a permanent marker refill with water-resistant performance, so it is built for marks that need to hold up better than basic office markers.

This refill pack is best for users already invested in the Pica VISOR permanent marker platform. It is not a standalone marker body. If your marker housing is still good, this is the cost-effective way to keep it in rotation. For shop work, layout, general marking, and industrial use where quick replacement matters, refills like this are the practical buy.
