Finally, a case that actually fits. The lids of the containers snap shut and hold closed well. Believe it or not, its incredibly comfortable beyond words. I used one set of long and one set of the short window brackets. I will buy more. If I tightened any more Im pretty sure I would shear the plastic threads off. And I dont have a wide foot by any means. I walked a mile with my cats in their stroller (hey, dont judge), and got 0 steps. These make my feet feel as good as my expensive tennis shoes. These types of slippers are so cool.
