I found what appear to be some good deals on Panasonic BD-Rs from a couple of eBay sellers, but I'm not certain whether they're of the same quality as the ones I've bought before (which, unlike these, were inkjet printable). I'm not concerned about the labels themselves (as I don't have a disk printer and have no interest in investing in one), but I'm not sure if these are as reliable as the ones I'm used to getting.
They are labeled as LM-BRS25LU25.
(There are also some of the inkjet printable kind that I'm used to buying for sale for reasonable prices from other sellers, but they are repackaged in paper sleeves by the eBay sellers, which I feel makes them less reliable than ones that are packaged in a sealed cakebox like this. Please correct me if I'm wrong.)
