Hi, I picked up the fun craft of making my own deodorant and would love to take your empty containers off your hands. Don't worry, I boil and sterilize them before using. Also, if you're interesting in buying some homemade deodorant from me (no Aluminum or chemicals!!), you can pass me your empty container and a couple bucks, let me know what scent you'd like (I have a couple different essential oils), and I'd be happy to make you some. Thanks! :)
