Great customer service, lots of flat back earrings options
I was looking for some flat back earrings that I can wear while sleeping. Kosiner had a lot of cute options in 14k gold. I got a pair of earrings and they were a little smaller than I wanted, but I was able to work with their customer service who provided me with a hassle-free exchange. I will definitely be buying more jewelry from this brand since their customer service was so easy to work with and the quality of their products is good.
