Format DIN A5 disc postcards (148mm x 210mm) can hold a regular sized CD or DVD (standard size). The DIN A5 postcard including a full size disc (M4-Card Maxi) weighs only 29grams. This is much lighter than any other packaging except paperbags.
This is a plus for Mac users who sometimes have difficulties to play Mini-CDs and DVDs in their Slot-in-drives.
