Using these knee pads is easy. Just wrap the strong double straps around your knees and adjust them for a snug fit. They're suitable for both indoor and outdoor work. When using, make sure the pads are properly positioned to get the best protection. Avoid using them in extremely sharp or rough environments that could damage the pads. To maintain them, clean the pads regularly with a mild soap and water. Let them air dry completely before storing. This will help keep them in good condition and ensure long - lasting use.
