I've been looking for some everyday hoops and couldn't decide between the 15mm and 20mm. I've been satisfied with every single purchase I've made here, and this one is no exception. The hoops are a good size for everyday wear! I like that the hoops look pretty dainty yet are very sturdy. Also the customer service is incredible. They were so great about showing me the two hoops and helping me with the exchange from the 15mm to 20mm. Would recommend!!
