Review (5/5): Good for cleaning aligners
I ordered this to clean my aligners while I brush my teeth at home. I only use this in the morning and at night (during the day I just rinse out my aligners). This case works for the reason I need it. I would not consider this leak proof unless you make sure that the lid is fully closed. There were a couple of times I went to shake the container and liquid spilled when I thought it was fully closed. I think this would be great for travel if you don't put any liquid in it once packed. I store an extra Orthokey in it to help me remove my aligners and the key fits fine inside when I'm not using it.
