To be honest: No
I have a series of bags in lots of colors, and I checked them, including how the seems were and the zippers (works with zippers).
It's so nicely made that you almost must search for the zippers. Hence you can wash them.
Since I'm a difficult guy, just checked one and can't find a label how to wash them ......
If I blow through them, that's perfectly OK and this fabric has some luxuary shade on it (feels very soft but rather strong and tight weave). I don't know about fire properties (maybe David can tell),
but those things look too nice to put my lighter on them (can still use them).
Hence I can't see what could be wrong with them.
Since they're that cheap, Scott at Studiotips tried them out and give a simple review, also making pictures, and was very positive.
It must be cheap to ship, since it are small packages.
The ones I custom ordered here (seemster) weren't better and as expensive (or cheap, whatever). And the first ones made is try and error (altering access a bit, too tight, too loose, too .....).
