A nap etc

It can be used normally. I use it in places where I hear the surrounding sounds such as when I take a nap.
Fields where noise is intense, durability tests on engines, etc. · · ·

There was a semi-transparent container with two pieces of digi-dump in a cylindrical one, but when putting it in a pocket by a single article, when wrapping it in a handkerchief and taking out it, Digi Dump will be on the floor and the floor It falls, rolling, dirty foreign matter adheres and I do not want to use it. It is likely to become otitis media with bacteria if you put it in your ear ... So, I think that there is also a tube of container to put in. If there is, I would like you to introduce it lightly. However, it does not mean to buy it immediately. Just in case, thank you.
