IKEA Billy Olsbo - Hinges? Description?

Hello,

I have two original packaged Ikea Billy Olsbo 501.813.95 doors from 2013.
Does anyone know detailed information about the contents of this product number?
I assume the doors are white and without panes?
Are the hinges positioned in the middle of the product or rather at the top and bottom?
I don’t want to open the boxes because I don’t need to and want to ship them in their original packaging.

Best regards and thanks.

From the Billy help:

BILLY OLSBO display cabinet door 40x35 cm. Push to open; no handles needed. Can only be attached to the corner element if the adjacent shelf has no doors. Hinges adjustable sideways and in height.

Regards, IKEA friend
