Not sure if anyone is still reading this. But I have one of the hasbro masks, and intend to make it into my shell.
I was curious as to what is the smallest size magnets people have had success with? I see most people using a 1/4 inch magnet.... most of those come in 1.4 lb pull force. I most likely will use these.
I do have frames though, that already seem to have a good lense in it. I'm afraid the 1/4 inch magnets may be a tad too big for the frame, and will mess up the lense, and I'd like to avoid that if possible.
Has anyone had success with 1/8th inch magnets... which normally come in 0.7 lb pull force? Concerned about those because the pull force is half. But maybe they are still ok?
If you can help, I'd appreciate it.
