Reply to Taking off Fader Caps Properly?

Hello again, Newbie with another question; As yesterday was my birthday, I got all my new toys. Black VCI-100, overlays, carrying case, etc. Anyway, I want to put the new overlays on and want to make sure I do it correctly. The fader caps seem to be on there pretty solid, is there a proper way to take them off so that I don't break, bend, ruin anything? Do they click in and come off a certain way?
