ER20XSC ER•20XS 耳塞專用額外收納盒

I grabbed this extra case to keep at my desk, so I always have a spot for my earplugs when I'm at the office. The hinge snaps shut firmly, which makes me confident they won't pop open in my bag.

Now I can keep my backup pair of ER•20XS plugs in this case and the main pair in the original. The hard plastic shell feels sturdy enough to toss in my bag without worrying about crushing the earplugs.

Bought this as a spare so I'm not stuck without a case when the original goes missing in my gym bag. It snaps shut securely and the earplugs fit exactly right, no rattling around.
