The hoop on this pair is approximately 15mm and the pearl charm can slide off so that this pair can be worn as the hoop alone, or with the pearl charm. Due to the handmade nature of the product, please allow for slight variations and imperfections from the pictured item– no two pairs are the same! While polymer clay is a durable material, if put under pressure or bent, it may snap and break. A care card will be included in each package, and care instructions are also on my policies page here...
