I am just a week into my invisalign treatment and I'm a little overwhelmed by all the stuff. Now I have to carry the case for the trays, toothbrush, paste, floss and more with me everywhere. I don't want it all swimming around in my purse. There has to be a good solution. Has anyone found a cute pencil/cosmetic case that is the right size? I almost bought a pencil case online but I figured it might not be big enough to fit the tray case. So far I've been keeping everything in a very un-classy ziplock bag stuffed in my purse. Thanks!Kat
