I wasn't sure where to post this so I figured I would go to the source. Most of us have a few old mascara tubes in a drawer we need to toss.
Please do not throw away your old mascara wands. Instead clean just the wand with dawn soap and place in a ziploc bag. Mail them to a Wildlife Refuge accepting donations. These little wands will be used to clean away oil, larvae, fly eggs, mites, infections, mud and other contaminants from wildlife. Works great for medical care and wound treatment
