The 2-pack of Primera Ink Cartridge Garages lets you keep your cartridges from drying out when they're not installed in your printer. They seal the cartridge nozzles by capping them with a cartridge garage. They're also useful when swapping pigment and dye cartridges. These garages support cartridges from the Primera IP60, LX600, LX610, and LX910 label printers. One garage is required for a single cartridge.
