This is a good quality carrying bag for six standard-sized microphones (perfect for the Shure SM57 or 58, for example).
Be aware, though, that even if it is well built, and has a good overall finish with soft pads and internal subdivisions, it is not intended for heavy-duty usage. It WILL, of course, protect your mics better compared to carelessly throwing your equipment in a box or in some bag full of other stuff. But as the sides are soft, they won't handle hard impact very well, and should be transported with minimum care to avoid damaging your mics.
Anyway, if you have a set of vocal mics, or some equipment of similar size, this bag is very good for a low price. Thomann has proven to build excelent acessories, cases, bags and so on, from what I can tell by my own experience (I have a Bass Elite Case, and have checked some guitar and gear cases from Thomann as well).
Just make sure is the kind of protection you need, and you're good to go with this.
