6 SETS! I priced these in the stores and this is quite a bargain. My grandkids still hold their noses when they swim, and that makes it hard to do tricks, or dive for things when they are using one hand to hold their nose. The nose clip makes a very tight fit, so no air is going up their noses. I don't know how they would work if you had a really large nose, but the do stretch out to where they fit my whole family. We have a pool, so the more sets I have the better. Each set comes in it's own clear box with the nose plug and two very nice ear plugs. I can't get water in my ears, so I really appreciate the way these fit. So, six sets for this price is a GREAT bargain!
