About Ayumi 8cm single

[Iyreen]

I just want to ask fellow collector expertise here about the 8cms singles.
How actually the cds are packaged? Izzit the cardboard are just sealed with only plastic bag, or hard jewel case?

I've seen some with seems like sealed with only plastic wrap bag like this:



but I also found those that got hard case like this one which is pretty nice imo:




So want to ask whether the actual brand new come with hard case or just plastic wrap? Hope somebody can answer my doubt here. Thanks a lot.
