Frequently when I get chips in the mail, the sender has used scotch tape to keep the chip in a plastic 2x2 holder or in a plastic page. Please don't use scotch tape anywhere near chips. If the chip comes into contact with the tape, it will leave a sticky residue on the chip. Over time dirt and other stuff will become attached to the chip. Instead use the 30 slot plastic pages, cut up for smaller amounts of chips if neccessary, they hold the chips firmly in place without the need for scotch tape.
