The wooden boxes are HEAVY. We've checked all major carriers and found the best rates but At over 4 lbs (1.8kgs), high shipping costs are unavoidable. For example, shipping to the UK was quoted at $56 USD.
In general, we're not a fan of shipping heavy things around the world for no reason. For future editions we hope to fix this with local manufactures. If you want to be part of this, check out our "Shipbuilder" reward :)
