I really wish I would have taken the time to return it. I included a picture of my glasses with the muff so you can see how it pushes in. I owned many pairs of them growing up. I was looking forward to the product and am sending it back tomorrow. For instance, he takes advice from cartoons on his nuclear weapons and holds his own Olympic games where he shoots his competitors and the referees to make sure he wins. I am (dreading) looking as I enter my room every night that I am going to see it collapsed. Good product, recommend for a modern, sleek design. I use them to store a wide range of small items that would otherwise overload and clutter my small sink cabinet. As for the top I was a little worried that it would keep coming off, but it came equipped with an adhesive gel patch to attach to the top of your case. 3 stars are mainly for the issues i came across.
