Buggy Bands for a camping trip
Size: 1 Count (Pack of 12)
Because of my experience with bugs loving me and using similar buggy bands to ward them off, I purchased these Buggy Bands for an upcoming camping trip so I can enjoy the great outdoors without the side effects of the bugs.

Don't buy they don't work only 3 hours that's it
Size: 1 Count (Pack of 12)
These are cheap and when I went to take it off it broke they only last three to four hours that's it then the scent is gone. I have bought these many a times from a different seller and they last me a long time matter of fact I got them at the Dollar tree
