For once I know, there are 2 different type of miwa's CD, first press and regular. How to see the differences the CD just from seeing the cover? Here's a little tutorial for you :p
When opened the CD, you'll find that miwa's always have a color tray for the CD, like this.
Little Girl and chAngE first press
don't cry anymore regular packaging
But to see the inside judging from the covers? Since the color tray is hard to see because of the obi, you'll not recognizing it easily ^^a
First, see the obi!!
a sample for a regular one
At the red lines I've pointed in the picture, you'll not seeing anything~
But the first press will have a written like "
初回" at the obi
don't cry anymore first press CD
the example is going with Little Girl and chAngE too
Little Girl obi First Press with color CD tray
chAngE obi First Press with color CD tray
Hope this help for you who's gonna collect miwa's CD
