All the pledge levels with rewards that weigh under 2kg have an additional cost for delivery outside the UK. The additional amount is listed under each pledge level. All overseas rewards will be posted by airmail. Parcels sent outside the EU will have a customs label added with the full value of the basic pledge level written on it.
Some of the higher pledge levels have rewards that weigh more than 2kg so there is no overseas delivery option. I'm happy to offer these rewards to overseas backers but please contact me first so I can provide a delivery price (which would need to be paid by paypal prior to dispatch).
