Take a look! I recently ordered some roll on glass bottles from Amazon (seriously, is Amazon not the best thing ever--I never leave my house to shop anymore--further building my social hermit-ness!). These things are so great and handy. I made my own little stash-able life savers to get me and the fam through the day when we're away. Super easy to do too. Like, fool-proof. All of them have olive oil for the carrier oil--not my fave, but it's what I had on hand.
