I also do this. A little tab on the scotch tape makes it really easy to peel off. I recycle as many things as possible when trading, bubble mailers, top loaders, team bags, penny sleeves. Heck, if you think about it, we're all recycling our doubles that we trade away!
Thanks everyone for keeping this an interesting and clean thread.
Thats what i do. Please for the love of everyone. Please if you use scotch tape please put a tab on both or at least 1 side so it can come off.
