This looks like MCC/MKM. It follows the format of other Mitsubishi Kagaku Media product numbers, though it doesn’t match exactly with any 1 found on http://www.mcmedia.co.jp/japanese/technology/dvd-newlineup/products_03_dvd-r_dl.html [though, apparently, they have a new product lineup]. Products using MCC/MKM technology under the Verbatim or Mitsubishi brands will mention “Mitsubishi Kagaku Media” on the package.
Then there is Mitsubishi Electric, which isn’t part of the MKM/MCC group and uses lower quality media not made with MKM technology. This media will just be branded “Mitsubishi”, with no mention of MKM anywhere on the package.
I’d give benefit of the doubt to it being MKM/MCC, assuming the seller used a stock product image that matches the real product.
