This plastic veil hides the head of the screw in the "locked" position. As an Arizona elementary teacher, I wear croc sandals almost every day. I would purchase again and will most definitely spread the word. Also unlike some of the others I’ve purchased the stitching and quality of the zipper was top notch. With many foot, leg, back injuries/conditions, shoes are important. This body wash lathered up nicely and rinsed off without leaving any kind of film or making me feel slippery. But after washing the first time before wearing they both lost their shape and looked old. So what can i do, i ordered another one again. Im sure it will hold more than the 150 lbs it is rated at. Kids will seat on the bench to tie shoes they wont spread the unclean shoes every where perfect to keep it in front of garage door.
