Review on Blue USB Flash Drive Case Organizer - Thumb Drive Holder, Memory Card Storage Bag for 28+ Sandisk Thumb WD and Any Flash Drive, Hard Drive Electronic Accessories Box by Ken Kowal

I agree with those who wrote that the side mesh pockets are too small for some USB sticks, PNY incl. And I have to be careful with PNYs to put them under the straps (middle part) so that the key metal part doesn't fall out; I had to stuff them back into the plastic sleeve. He's too tight. I've just received this item so I can't comment on strength or durability (whatever that difference is) and I won't be using it for travel. But I'm concerned after reading a review that said it fell apart.
