I use the 2 1/2" x 2 1/2" cardboard flip holders with the 44mm window. (Works good for Palms chips.) I do not staple them though. I fold them over and use two 1/2" x 3/4" Avery "All purpose labels" on the corners. That way the chips can still be removed without ripping out a staple. They can be found at a Wal Mart, Shopko, etc...
