I've always carried around my scleral lens supplies in a black cloth pencil/bankers bag, and it served me well, but when I saw this bag from the Dry Eye Shop, I had to give it a try. And I'm glad I did! The size is perfect, and even allows me to carry around a few extra items that wouldn't fit in my old bag. Plus, it has an extra zipper and an inner pouch so I can keep things like lid wipes and alcohol pads separate from the many bottles and vials and other paraphernalia I've accumulated.
