Yes. They will peel off. Just get them started with your thumbnail. Any remaining adhesive can be remove with a rag dampened with rubbing alcohol.
I just ask you to pay for the additional cost of shipping. Standard post to Canada, the Americas and most countries in and around Europe cost around 10 USD.
To pay the extra amount you can either:
A) Add $10 to your pledge and message me on Kickstarter.
B) Pay later via Google Checkout once the Kickstarter project is fully funded.
