vintage tamagotchi screws

[tamafan325]

Hi guys I have a question

I'm getting an angelgotchi soon, and i was wondering, i heard vintage tama's screws are softer and easier to break, do they also have that round "label" around the screw on the inside of the tamagotchi? and if so, how do i get it off to schange the screw, because i heard the screw of vintage tama's are softer, and i don't want the screw to break

Thank you in advance
