Just sold a few cards on ebay. Can anyone help me determine how much one card in a card saver 1 weighs in a bubble mailer?

Next can anyone tell me how much one SGC graded card in a bubble mailer is?

I wanna use the ebay label thing but not sure. Tried one and put 7 ozs for a raw card which I think is too heavy.
