These mushroom earrings are made with charms produced in Japan. They are sold as a single earring, one piece. The mushroom height is approximately 1.1cm. Made of brass, they are quite cute. I also have single earrings featuring cats and mice for sale. Due to the high cost of materials, I am unable to offer a discount, so I have set the price to be a good value from the start. Thank you for your understanding.
