It is customizable, printed in Stainless Steel and it supports standard butterfly clutch.
Of course the butterfly clutch is not included, but I am sure one day Shapeways will offer this service.
In the mean time, just find any old lapel pin, keep the butterfly clutch and change lapel pins for a customizable one!
It is quite small (2.5x1.0cm), it supports up to 8 or 9 characters (including spaces) and it is affordable.
I will probably make a less wide version for writing only initials (2 to 3 characters).
