Iv been selling cards and I do all the good things a seller should, Top loader with painters tape, I don't try to make more money and overcharge for shipping ect ect. Iv bought enough and read r/baseballcards enough to know what is expected. My question is, when using an envelope, how do you all feel about using double sided tape on the back of the Top loader to ad hear the top loader and the envelope so there isn't a bunch of "sloshing" around from the card in the envelope? I just finished a large batch of cards to be shipped out and used double sided tape and I know its probably a real pain to get off when it arrives but at least the card is a bit more safe? Or it seems that way to me. What say you?
