This is a pair of French clip earrings in an antique bronze finish and features a 2018 stamp from Japan commemorating Eric Carle's children's book, The Very Hungry Caterpillar.
The images were taken from a real, used, vintage postage stamp and may have post office cancellation marks.
Size of earring is 18mm and they are lead and nickel free.
Earrings are water resistant but not waterproof, I recommend removing before showering, bathing or swimming.
