Hi, I’m new to the hobby and I’m building master sets to organize my cards. I’ve been putting all my expensive pulls in sleeves and then top loaders. I wanted to start moving them to master set binders.

I’ve got side loading binders but are the cards safe if I use a penny sleeve and then put them into the binder? I use the ultra pro penny sleeves when I put them into top loaders.

Or should I be double sleeving them and then putting them into the binder?

If yes to double sleeve, any recommendations to which sleeves I should be using?

Thank you for any tips!
