If you can't store your chips in racks or tubes for easy access, putting them in the 2 1/2 X 2 1/2 cardboard flips and storing them in boxes works for me. The less PVC plastic that comes in contact with your chips, the better. Something in the formula for the flexible plastic flips has a tendency to "bleed" the color red in casino chips made by PaulSon and Chipco into the surrounding areas of the chip as well as into the plastic holders. Keep them out of direct sunlight no matter how you store them, the sun will suck the color out of a chip quicker than anything else!
