Obi-less releases?

[sxesven]

Mainly curious because I just don't know or remember for some releases.

I went through my physicals recently and found that for a few releases I don't have obis. For some that makes sense: a few years back I bought some second-hand releases off another user here and I seem to recall that for some he just didn't have obis anymore. No mystery there. For some of my own now I wonder though. What about A BEST and A BALLADS? (My versions of this are Taiwanese by the way: AVTCD 95461 and AVTCD 95676.) These come in a slipcase; perhaps they never had an obi at all?

I also just received a second-hand copy of Love songs, which also is in a slipcase. Does that also mean no obi?

And are there any others? (Or any at all?)
