I use these funnels to refill my empty Beautycounter product bottles. I like to keep one bottle in my shower, one in my bathtub, one at my sink, and of course, my Countertime Mini Travel Set. This way I can wash my face no matter where I land at the beginning or end of the day. These stainless steel funnels are not only safe from toxins, but are also the perfect size for transferring from bottle to bottle. See my Facebook Video demonstrating how I use them.
