If you need reliable labels for your Brady printers, this two-cartridge set has you covered! You get both the M21-500-595-WT (0.5\\\ width) and M21-375-595-WT (0.375\\\ width) vinyl label cartridges that work perfectly with BMP21, ID PAL, and LABPAL label printers. These aren't your average stickers - this is serious industrial-grade stuff. The black text on white vinyl tape stays put even in freezer environments and on textured surfaces, plus the permanent adhesive handles grease, oil, and most industrial chemicals like a champ. What's really handy is how well these stick to pipes, walls, equipment, and even curved surfaces without peeling off. They're made from durable film material that conforms to irregular or rough surfaces, making them perfect for general identification, laboratory labeling, pipe marking, warehouse signs, safety panels, and warning tapes. Each cartridge gives you 21 feet of continuous tape, so you can label everything in sight without running out too quickly. Whether you're in manufacturing, electrical work, or just need professional-looking labels that actually last, these Brady cartridges deliver the quality the brand is known for.
