Fits everyone
The earplugs can fit almost every wearer and are very comfortable.
Cost effective
Unlike disposable earplugs, these reusable earplugs can be used until 
they are damaged, reducing the cost to the minimum.
Reusable storage case with bead chain
When not in use, ear plugs can be safely stored in the ear plugs box to 
prevent them from going missing, In addition, the reusable case with bead 
chain means users can attach it to a belt loop, apron, bag, key chain or other handy tool.
Better communication
Low attenuation is ideal for medium-to-low noise environments, preventing
worker isolation by enhancing communication and improving overall worker safety and compliance.
