Needless to say, what you can see on the photos is just a white sample box to calculate the exact size. But look at this beautiful thing. You get an idea of how the final box will look like.
I requested another sample since I'm not 100% happy with the size right now.
We are just talking about 2-3 mm (0.08 - 0.12 inches) which are too long on one side and too short on the other.
It would be easier to calculate the exact size with a Bicycle brick but it seems to be pretty difficult to get your hands on a Bicycle deck in China. However, I like the speedy process.
