facemasks

I know I have been away from the hobby for a while so I was looking at miggles site for uniform numbers and saw facemasks and got to thinking wow has this changed. The way it appear they sell them in a variety of styles with 33 in a pack? Are they different colors? How do you apply them, super glue? If it were up to me I would get those, however, my wife might think differently, HA Also notice they don't sell NFL teams anymore, Some other company selling them now? No biggie I tend to enjoy painting my own, but was currious, Thanks
