Packaging
These came to me in fairly standard packaging- just a flat, wide rectangle of cardboard with a picture of a model wearing the pantyhose, which was wrapped in plastic. Super basic, no frills. It is not necessarily a discreet package, but is not at all pornographic- just obviously a package of crotchless fishnets!
It was easy to open and get the pantyhose out, but one leg of the pantyhose was stretched over a piece of cardboard (as stockings are often displayed) which did stretch it out some. I always hate when pantyhose are packaged that way, but such is life!

Quality
These seem to be of decent all around quality. They are a cheap pair of pantyhose, so don't expect top of the line work here, but they're pretty darn good for 4 bucks! The material of the fishnet is very soft and is actually not my favorite type of fishnet- it's made of thin, soft fibers, which makes it very comfortable to wear, but these fibers will, through a little bit of wear, eventually stretch out and not cling to the legs quite as well as they ideally should. This is my only real complaint with these- it's not sexy to be standing there with baggy fishnet bunched around your knees! This bagginess, however, will easy be fixed by washing and drying these thoroughly.
They seem to be reasonably durable, as well. While these will snag if caught, as most fishnets will, they are more or less resilient and can take a bit of abuse (not much, but you don't have to treat them like delicate little things!) feel free to do a bit of rolling around with them, and of course if you DO get runs or tears, hey, just pick up another pair!

Fit
These fit me splendidly. My measurements:
Hips: 38"
Thigh Circumference: 24"
Height: 5'7"

I tend to wear a large in most clothes, and tend to think of myself as a bit of a bigger girl. These fit me really well, and I think they'd fit someone smaller or larger without much problem. If you are especially petite or plus sized, though, you might want to be cautious, as these might not be an ideal fit for you.

Comfort
I find these quite nice to wear. Aside from the bagginess that happens, they are soft and feel nice on the skin.
And, as many of my fellow fishnet wearers know, fishnets will hurt your feet after a few hours of wearing them and walking around. These, thankfully, are soft enough that I have not had that problem at all- they don't cut into my skin one bit!

Special Features
Of course, I'm sure you're all dying to hear about the crotch!
The opening is quite large, and exposes about half of my (sizeable) ass. I think that anyone would have easy access to any intimate parts they might want while wearing these, which is great! They definitely don't get in the way for vaginal intercourse, and while I have not tried anal sex in them, I imagine that would be easy as well!

Care
I just toss these in the wash in a lingerie bag, and dry them on air only. So far, I've not had problems with this method. You can also hand wash these and hang them to dry!

These are OK for short term wear or something, but the fact that they stretch out so much over a few hours, and don't shrink back, has me not wanting to wear them. It looks bad!
