This enamel pin, featuring the beloved Earl-and-Mooch yin yang symbol, measures approximately 1" in diameter and includes a butterfly clutch metal back. It is crafted using a "soft" enamel process, in which the cavities are partially filled with enamel to maintain raised and recessed areas to the touch. Use MUTTS pins to add flair to jackets, purses, backpacks, hats, lanyards, and more! Each comes packaged on a 4" x 5" quote card. Perfect for gift-giving!
