Hi tiede, welcome to CD Freaks!
R8X-DH-05-19 395 is not a legitimate Taiyo Yuden hub code. :disagree:
Taiyo Yuden's original packaging has never used brown tape for sealing.
Please return them to get a refund.
Were these actually sold as "Taiyo Yuden" or under some off-the-wall brand like Mirror or Sonic?
