3M Earplugs are ideal for situations with loud or discomforting noise levels.
Attention : Hands and plugs should be clean before fitting.
ROLL plug slowly with thumb & fingers (fig 1). Gradually increase pressure to COMPRESS plug to a very thin crease-free cylinder.
INSERT compressed plug well into ear canal WHILE PULLING ear outward & upward with opposite hand (fig 2).
CHECK FIT after plug expands in ear. TOUCH plug. You should feel only the end of plug (fig 3). If you feel most of plug outside the ear canal (fig 4) remove plug & repeat fitting.
