I love how smooth and rounded the ring feels. It’s comfortable to wear at anytime.

I’ve ordered several rings from Studio Cult & I’m never disappointed. They are well made & high quality. I wear them almost daily & they’re just as shiny as day 1, & I am rough on jewelry. I wear 3 of the Roundth or Squiggle rings stacked & I’ve gotten so many compliments on them that I just decided I need 2 more.
Pro tip for neurodivergent baddies- the Roundth & Squiggle rings are better than any fidget ring on the market when stacked in multiples. They’re so perfectly round & symmetrical that they spin well next to each other (as long as they’re not too tight). Roundth has a soft, fidget spinner type spin, whereas Squiggle is obviously clicky because corners. They also make delightful little metallic *ting* when they click together. 10/10, will wear forever.

This ring is simple into the point and you can wear it literally would everything. I basically wear this ring every day and I love it and matches literally with everything like I said it doesn’t roster tarnish and I love it.
