A Song for XX and RAINBOW album question

[nomizo31]

i have japan first press of a song for XX and the case is slightly thicker. maybe 2-3mm thicker than a normal jewel case.

The cover is printed on metalic paper (real silver colour) the reason the case is thicker is bcos they make more room for the booklet. it is not overly thick booklet - its just that it is slightly heavier paper - better quality and they didnt want to press it too flat to fit in a normal case.

Hope this helps-- if you have n e more q - ask ne? ^^
