A Twitter account under the username @LILDOUBT1 has tweeted about used mascara wands to give to local wildlife refuges.
Please do NOT throw away your mascara wands. Instead, clean JUST THE WAND with dawn soap, place them in a ziploc bag and mail them to a Wildlife Refuge accepting donations. These little wands are able to be upcycled to clean away oil, larvae, fly eggs, mites, infections and more pic.twitter.com/ezXgbPwFTD
