Tips & Things to Consider

  • If you know your knuckle is on the larger side, consider getting one size bigger. Otherwise you might not be able slide the ring through well.
  • Due to its handmade nature, the inner diameter of the ring will vary between 1 to 2 mm.
  • Measure your finger multiple times to ensure accuracy. As your ring size does fluctuates depending on temperature - it can be smaller when you are colder, and slightly bigger when you’re warm.
  • If the size does not fit well after you have received your ring, drop us an email at hello@kollidea.com within 7 days so that we can check if an exchange for another size is available.
