About the Artist

Hello! I’m Caitlin, a jewelry designer, illustrator, and graphic designer living and working from my home in Portland, Oregon. Poptone is a line of playful handmade jewelry, ever-seeking the quirky and joyful. I began experimenting with jewelry design in 2016 and soon launched a small collection of stud earrings as a fun side project, which grew into a thriving business. In 2017 I began selling wholesale to boutiques, indie book stores, and museums across the United States.

Each piece is designed and hand-illustrated in-house my me. I take great care in the quality and detail of each earring, pendant, or statement necklace. If you think that Poptone could be a great fit for your shop please fill out this contact form. I look forward to hearing from you! -Caitlin Kastner

My 10 year old wore these for her 10 yrs old pictures and have not stopped wearing. She typically cannot wear non-gold earrings for a long period of time without pain inside her ear; she had no problem with these! Will definitely be getting more! Perfect size for older child and adult. Love them!

I love these earrings! I've bought 3 pairs (paper planes, rockets, and the love messages) and they're all super cute, and they aren't fragile like some of the other earrings I've bought in the past from other vendors.
