I don't have the answer yet. But I am right here asking the question with you.
Hand drawn and sealed with an enamel varnish, so you can wear as often as you contemplate the confusion of existing.
Measures approx 1.7cm x 2.2cm at its longest/widest points.
This pin is made to order, so you will receive one like the one pictured. Because they are handmade, there may be slight differences in size and detail from one to the next.
