I have had the Eldorado chip in an airtite since 2004 when I converted my entire collection to airtites with rings. I pulled it out this morning and checked the case , no sign of bleeding was found. I live in a cool climate on the central coast of California and it rarely gets over 80 around here. I found that when I took chips in flips to a warm climate, like convention or the Los Angeles area, the bleed seemed to happen faster. Don't know it that's real or just me. I have not seen a bleeder since switching to airtites back in 2004 /2005. Plactic flips of all kinds and manufactures have shown signs of bleed, have some of the traders in them now, but none of my better chips. Will wait and see what the future brings. Take care Jim.......
