Bought the mofi sleeves from Amazon. 50 pack for less than $20. For the most part they are fine, but it seems that some records are too large, and a bit tough to slide in to the sleeves. Seems like older records fit fine, but new ones from the late 70s into the late 80s (when I more or less stopped buying vinyl) are a bit tight. Overall they are great though and I'd buy them again.
