Worldwide Militaria, LLC: Medal Sleeves
However, I question the seller's statement that the envelopes will not cause tarnish simply because they are non-acidic...PVC is the real problem with plastic and this seems to be the kind of soft plastic that does contain PVC. :confused
Groups on a bar are actually easier for me to store: I put a non-PVC "SAFLIP" plastic sleeve on each medal and put the entire thing into an acid-free paper envelope.
