At the end of the project you will receive a survey where you will have the chance to let us know precisely which combination of materials and finishes you are backing for. There will also be fields to let us know of any additional requests (i.e. asking for a non-engraved mechanism) or just to tell us your favorite joke.
You can mix and match when you purchase the multi-pen rewards (i.e. 3 titanium and 1 copper) but if you just want to add a pen or two simply add the amount of the additional reward to your original selection (i.e. If you want 1x Titanium pen and 1x Brass pen: Back $100 for a titanium then simply add $96 for a brass = $196 total for both pens) and in the final survey you will have a chance to let us know which materials and finishes you backed.
Sadly, because that's exactly how much it costs us. We've found that the fastest, cheapest and most secure form of international shipping is the USPS International Flat Rate Box which is $32 from the US to most locations (turns out that Canada is only $26... my bad).
This method is secure and has good tracking. We've also yet to lose a package this way so we feel this is the way to go (even the Austrian package that somehow got redirected to Australia finally turned up).
In our spare time we're actually working on a laser death ray which would be suitable for deployment on properly trained marine life. At the moment we're experimenting with angry sea bass but find them to be a bit small and thus ill suited to the large power cell required for the laser. We are considering moving to a larger predatory fish for the next phase of testing.
