I’ve seen a couple of copies of these floating around in the past and sellers always ask absurd sums. I stayed away as the label seemed somewhat questionable to me but over time read a couple of things here and there that lead me to believe they’re legit. Recently one came up for a very reasonable amount so took a shot and now it’s safely housed in my usual Japanese rice paper inner / white Cardboard outer / Japanese outer sealed sleeve combination that protects all of my 45s (more on that another day as I’ve been asked before how I store things).
