If you want these in one (pair) offs to try I carry them in stock these days.
Can post worldwide for £1.50 per order
Cheaper in bulk from Shapeways but postage more.
One day I'll fix my online shop so people can buy these there, until then PM me.
To know the meaning of life you need not to be dealt a good hand, but rather to play the worthless hand you have been dealt to the best of your ability.
