**PLEASE READ**
If you are going to take the shells apart for any reason you need to read all of this. Due to the material or manufacturing process of these shells they are harder to get apart than old commercially produced VHS that we are used to. More care and time should be given when taking these apart in order not to damage the exterior of the shell. I recommend you take a quick look at the short youtube video I made regarding this issue here : https://youtu.be/kR6X9M3u6OI
I would recommend using a small plastic or metal pry tool like you would use on other small electronics to disassemble these shells, espeically on the center most screw post. Please keep in mind that if the center post breaks during disassembly you can still reassemble it just fine, you just need to be careful not to bend or twist the shell itself or you will crack the shell.
