There's also a very nice chap in Providence RI (Andy's Record Supplies). You'll find his ad in the 1st 2-11 pages of practically every Goldmine. Take a peek with a pen at your local book store and write down his address....His rates for CD or LP Mylars are good too. It's all he does, so he's rarely ever "OUT" of anything.
He now has, I think, a $30 minimum. I buy the LP fitted "Seal King" style for my Lps and LD's. They're great, but very essential for cardboard Japanese LP replica CDs and the like.
People have been known to use certain Ziplock© sandwitch bags, and although they're not as classy and neat, resist moisture. He has no website, but he's listed here (
