I've been having a rough time finding GOOD, durable sleeves for Laserdiscs. Normally, you just see those tiny, thin poly sleeves that are advertised as 'heavy duty' when in fact they barely offer any protection at all. The kind I want is in this pic. They're the thickest and best for the job from what I have noticed. But I have no idea what they're called or how you can find them for sale. The ones I have came with the LDs that I bought used. Does anyone know where I can find these kinds of sleeves? (with a flap or not.) P.S- I've also seen (and own) a few Zip Lock Bag Sleeves made especially for Laserdiscs. Anyone know where you can find these? I would GREATLY appreciate any help!
