thickest outer record sleeves, where to buy them?


hi,
3 or 4 years ago I bought a very thick outer plastic sleeves for my records. They can stand upright without a record inside and they are 100% crystal clear transparent. Im trying to find those same sleeves in the market but I can't... can you help me please? thanks in advance

I got 5.0 ml ones, and I actually don't like them. They are a harder, stiffer plastic. So much so, that they are a pain to work with. They would be cool to display an album, because they look very clear, but were not practical from a convenience factor. The ones I have are exactly what you describe, they can STAND UPRIGHT on their own. I will double check, but I am near positive I got them at SLEEVE CITY. If you can't get them, I will sell you mine for what I paid for them. Just curious, why do you like these?
Sleeve City does indeed sell the 5 mil ones:

I agree with you about the thickness being too hard to use. I tried them many years ago and went back to the 3 mil sleeves.
thanks for the responses. About the reason why I like them more honestly dont know: maybe I consider thiker sleeves protect better?, maybe Im use to use them? ... dont know but I like them more.
