Bigger, Better

I want to trade ten plastic buttons for something more valuable. Each button will go to a different country - ten different countries! I have already chosen five countries - Finland, Australia, Canada, Thailand, and China. I invite you to suggest five more countries whose people are open and willing to participate in such a trade. If you have something valuable that you are willing to offer in exchange for my buttons, please contact me. I am open to dialogue and ready to consider any interesting proposals. Thank you!
