Hello I had collection paperwallet.
Does your guys have suggest to do cover paperwallet?
Does laminating it's good idea? I'm not sure about it, might that's could force the security password.
Sorry for not good language, wish you guys understand what's my point and reason why I've not good language.
More important is to keep those notes in an area relatively uniform temperature and humidity out of direct sunlight. And to store then I would suggest you use mylar holder so that you would not have acid exposure.
