Can I use beer coaster differently?
Write something and send it to your friend. Also, it might picture a beer brand located in a certain region, so it definitely works similarly to a postcard.
Kinda a bad one
4. Christmas tree toy
6. As a spoke card for you bicycle
Well, to put it within the spokes of your rear wheel
7. As a secret code/sign
Instead of a password just hold a specific coster

You will need 4 decks of a certain amount of costers
9. Cat toy
Your cat can drag and push it across the room
