My personal collections which is every casino I have ever "Gambled in" are all in the Air-Tites with the "WHITE RINGS" - most have been in these rings for over 2 years and I see NO DEGREDATION, TONING due to leakage of air which creates "OIXIDATION". THEY ARE AS BRIGHT AND SHBINEY AS THE DAY THEY WERE PLACED IN THEM. Many "True Ardent Professional Collectors will as stated by several use the "Direct Fit". I do likjewise if I am selling these strikes. I display my Collecion for my friends, and visiotrs can see when the come into my home and do not bury them in a draw or box where they cannot be seen with the mind-set, that I have all of these and all of those etc., but who cares if you can't opuyt them on display? That is my personal assessment.
