Do the CDs have visible defects (fingerprints, dust, dye defects, scratches)?
What does the cakebox look like? Does it look like CMC, MBI or Made in Luxembourg TDK?
(The CMC cakeboxes have a high edge on the top, and the Made in Luxembourg cakeboxes have a smaller font than the MBI one but all in all look similar. The Made in Luxembourg cakeboxes have a five-lettered code above the recycling sign on the bottom.)
