These Stanley Pre-Shaped Foam Earplugs deliver an excellent noise reduction rating of 32. The yellow and lime color scheme helps prevent misplacement by making them easy to spot when not in use. The earplug's contoured t-shape makes for quick earplug insertion and removal, and the smaller profile is ideal for smaller ear canals. The foam earplug is also self-adjusting to fit most ear canals. The jobsite dirt buildup is inhibited by the soil-resistant, closed-cell foam skin. The ear accessory comes with an 80 pk. tube of earplugs. The pre-shaped foam earplugs have comfortable wing shape for universal comfortable fit and the extremely soft form has a low-pressure fit. This ear hardware is made in USA.
