The Epson LK-4YBW is a LabelWorks tape cartridge designed for creating highly visible labels with black text on a yellow background. This 12mm wide tape extends for 9 meters, providing ample material for a variety of organizational tasks. Its extra-strength adhesive ensures a secure hold, while the durable media is specifically built to withstand outdoor conditions without degrading. To make the labeling process smoother, the tape features a split-back design that allows you to peel the backing away quickly and easily. The entire roll is protected by a sturdy hard plastic casing, ensuring it remains intact until it is loaded into your printer. This cartridge is compatible with a wide range of LabelWorks models, including the LW-1000, LW-400, LW-600, and the Z-series such as the LW-Z5000BE, making it a reliable choice for anyone needing long-lasting, weather-resistant markers.
