So if you use them in conjunction with the case, you are going to have remove and replace them every time they go in our out of the case. This is the best towel holder! Theyre really soft and the kids couldnt be happier. Top notch product! Worked very well for my little wall planter Repair needed will cost me more time and money in drywall patch tape, spackle and paint than the whole cost of the hook set. It?s held for the last few months. They sound great however I need them mostly for my phone (Apple 8+) and no one can hear me clearly on phone calls. I know they are plastic rubber type but should of realised because they are a real shoe not like the original crocs they make my feet sweat like crazy. But when set up correctly, it even hold my 185lb body.
