Secret Twincle is a Sydney-based handmade accessory brand creating colourful, lightweight jewellery from discarded plastic bottle caps.

Each piece is carefully handcrafted in small batches, transforming everyday waste into playful wearable art with unique marbled patterns and vibrant colour combinations.

No two pieces are exactly the same. Designed to be bold yet easy to wear, Secret Twincle celebrates creativity, individuality, and giving materials a second life.

Founded by Japanese maker Asuka Yamaoka in Sydney, Secret Twincle began from a curiosity
about how discarded plastic could be transformed into something beautiful and joyful.

Inspired by the colours and patterns of Australian nature - from ocean blues and native plants to tropical birds and vibrant wildlife - Asuka handcrafts each piece individually, focusing on light-weight comfort, one-of-a-kind patterns, and thoughtful small-scale production.

Rather than creating pieces people choose simply because they are eco-friendly, Secret Twincle aims to create accessories that feel exciting, playful, and beautiful first - pieces that people naturally fall in love with, and then discover are made from recycled materials.
