1. removing all the cards from the box
2. unfolding the box
3. rolling the box into a tube so it will fit into the bottle
4. unrolling and refolding the box in the bottle
5. roll each card, insert in bottle, unroll
6. put the cards back in the box
Of course, doing all this would be very tedious, and would be easier if one used some specialized tools, but it's doable.
