That’s all I use is the card board flips with the clear center round. I tape the top shut and don’t use staples. That way I can take them out easy and will never scratch a chip. Then I put them in the 12 to a page clear plastic holders and then into a 3 ring binder. Even those I have special plastic ones that I’m able to put a picture in the front back and inside, 3 ring view binder they are called. Plus you can write on the cardboard flips, such as price, catalogue # etc.
When I get a chip in a plastic flip I just take them out and throw them away. Most of the time I put them immediately into an airtight to protect them especially if they are of higher value.
