Just took a recent trip and didn’t have any travel size lotions that would pass through security. After looking all over the house for something that would work, I had the brilliant idea of using some of my extra contact cases. Works perfectly that close up tight so there is no leaking and they are the perfect size for my foundation, face lotion, hair gel and styling cream which I don’t need a lot of, but that I can’t do without. perfect for weekend getaways. and finally found something useful to do with all of my old contact cases!
