It is good to be able to adjust without being uncomfortable, as it is easy to use and it is used quickly. If you dare say it's OK to enter more than one so I want you to work harder on a more costly basis, just quality is good so please be sure to keep the quality! It is a very good product. You can use it.
I am using it to prevent damage to my ears due to noise of power tools

It is easy to use because it enters the room without twisting it. I think that this is the best when it lasts long lasting, is more usable than the ear muff and is also used as a mask, goggles, etc. But the price is a bit expensive ... I think that it can not be made with around 100 yen.
