This gorgeous collar set features branches from the Paulownia, also known as a Royal Princess/Empress tree. Traditionally, when a young girl was born in Japan, especially those of Royal blood, a Paulownia or kiri, was planted. This was because Paulownia are strong, resilient trees that also yield a strong wood with a lighter color than most other hardwoods. Our pin set is a reminder that you too are strong and resilient and deserving of only the best! this set is available in a classic purple or our black-and-grey irezumi style variant.
