Get the Lead Dog brand for thicker plastic. Cowen used to be the best but they remade their dies and now pockets are too small for a chip.

You don't need a flip or cardboard holder this way. You get 2 1/2 times as many chips per page as with the 12 pocket pages and cardboard holders.

Some will tell you plastic pages damage your chips. I have no problems after 15 years.

For your best chips, use a Dansco binder which has thick pages and diecut openings for the chips. Rigid plastic covers slide over each row of chips. Expensive, but classy.
