a 30 ml bottle for $14.95 or a packet of 5 for $6.95. I promise you this stuff works. I have put it to the test. I have wore my balaclava to my huntin spot on my 4-wheeler with it pulled up over my nose. I have pulled my neck gaitor up over my nose on stand, and not once did my glasses fog up. this is one of them try it to beleive it deals. also, after your first order, you can use your e-mail address as a coupon on your next order and get a packet of 5 for free. now. I can even use a face mask again without worrying about fog-up. ya'll got to try this stuff.
