3.5 mil in the description
Nitrile has a higher puncture resistance than latex. Nitrile also has a better chemical resistance than Latex or Vinyl gloves. Latex comes directly from rubber trees and is a potentially lethal allergen for some people, where nitrile, a synthetic material that feels like latex, is non-allergenic.
They are only 3.5 mil thick so they may be too thin for harsh chemicals? I bought them for chemical use and read the same thing before use! The harsh chemicals seemed to want to breech the glove so research what mil thickness will stop harsh chemicals? Nitrile gloves are used when you are allergic to Latex so I assume a thicker glove may be needed protect you.
The "full description" for this glove says "Cornstarch-powdered" - but the descriptions of the several disposable nitrile gloves on the Home Depot website don't match the product names with respect to powder. HomeDepot please get these product listings cleaned up!

Not this type but other brands of nitrile gloves
Yes. They are not sterile, though, so after you put them on wash your hands just as you would if you were working without gloves.
No, just by box
They do run smaller than most brands, if you wear a small, a medium would be on the border line for you, I have not seen these in a small!
