Pica 991/52 VISOR Luminescent Permanent Marker Refill, White (4-Pack) is a refill pack for the Pica VISOR permanent marker system. This is a permanent marker refill designed for restoring marking performance on dry and wet surfaces. Part number 991/52. If you already rely on a VISOR marker for jobsite layout, touchups, or clear identification marks, this pack gives you four white refills so the marker body stays in service.

What matters here is simple: this is not a throwaway marker. The refill format lets you keep using the same Pica VISOR marker while replacing only the marking core. For anyone marking materials regularly, that is the practical advantage. You spend less time replacing full markers and more time keeping a consistent marker in your pouch, truck, or box.

The white refill color is the reason many users pick this version. White marks are easier to spot on darker materials and surfaces where standard dark ink disappears. That makes this refill a smart fit for layout work, identification marks, and quick notes where contrast matters more than anything else.

Pica lists this VISOR refill as a multi-use permanent marker refill for dry and wet surfaces, and supplementary product data identifies it as waterproof with an oil-based marking formula. In plain terms, that means it is built for tougher real-world conditions than a basic office marker. If your work does not always happen on perfectly clean, perfectly dry material, that is the point of stepping up to this refill system.

This refill pack is best understood as part of the larger Pica VISOR marking platform. It is meant for users who already own the compatible VISOR permanent marker body and want the correct white replacement refills rather than an entirely new marker. That makes it a good buy for tradespeople, shop users, and serious DIYers who want a stocked refill case ready to go instead of getting caught with a dead marker halfway through a task.

Who should buy it? Anyone already using the Pica VISOR permanent marker and needing white permanent marks on mixed jobsite or shop surfaces. If you want a refillable permanent marker setup, need waterproof marking performance, and prefer to keep spare refills organized in one pack, this is the right version to grab. If you need a complete marker body, though, this refill pack is only part of the system.
