This is a genuine Hewlett-Packard (HP) LaserJet 131A toner cartridge multi-pack. The set includes a full range of colors: CF210A (Black), CF211A (Cyan), CF212A (Yellow), and CF213A (Magenta). These original HP cartridges are designed for high-performance color printing and are compatible with LaserJet Pro 200 color M251 and M276 series printers. While the outer cardboard packaging shows significant shelf wear and crushing, the individual cartridge boxes appear to be sealed, which is critical for maintaining the integrity of the toner. Authentic HP toner is highly sought after in the resale market compared to third-party alternatives due to its reliability and print quality. This set represents a significant savings over retail prices for small office or home office users looking for OEM quality. Note that the second image shows a different compatible 201X-4 box, but the primary item for sale is the original HP 131A 4-pack.
