After much thought, I decided to storage my nesties in CD envelopes. They are not the strongest but easily replaced and they don't take up a lot of room. This is the cheapest way I thought would solve my problem. (I would rather use my money on stamps and paper.) I used the packaging that came with the nesties and put megnetic tape to adhere the nesties. TFL!
P.S. Thanks for all your suggestions. I know I have said it before but I really appreciate it.
