Three sizes available to fit different desks and configurations. For safe handling, avoid lifting on the long side when moving. Material and finish: robust metal mesh with a polished surface and rounded edges, designed with no sharp corners for safe use. Easy assembly: tool-free installation. Attach by inserting the mesh into the right-angle metal plates. Non-slip stability: edge reinforcement with a soft padding on the underside helps prevent sliding and protects the desk surface from scratches. Use scenarios: - Desktop organization: keeps documents, notebooks, and small accessories neatly arranged and within reach without sliding. - Workshop or studio: provides a sturdy base for small tools or components, reducing clutter and improving workflow. - Computer workstation: acts as a protective, non-slip base for keyboards, laptops, or peripherals, preventing movement and desk wear.
