I bought these assuming they were still the top quality dark blue AZO dye that Verbatim used to make these with. I verified the product # against my old Verbatim catalog & the number is the same. Sadly, the quality is not. These are made by CMC Magnetics & are fine for disposable use. If you're looking for the 'good ones', these are NOT them. These are way overpriced for being common ordinary quality discs.
