Printed in White Detail and stained with tea (and excess color scratched off painstakingly with a fingernail. Not the most successful technique.)
This die is a shell surrounding a chunk of the support material, for cost purposes. It's 3cm in radius, which turns out to be a nice solid size for a die. The numbers look big enough to be readable, and it very decisively lands on a single face with a single face up. A handsome piece of random-number generation!
There's a 4cm version of this too, but I'm starting to think that might be overkill.
