The Limited Edition Keyring is the perfect souvenir to celebrate 35 years of Questacon.
Lasers are used to modify the surface of the keyring which creates an almost holographic effect. Read more about the process in 'Science behind the product'.
- Total size including chain: 8cm
- Stainless steel.
- Laser surface modification processed in Australia.
The keyrings are decorated by laser experts with several decades worth of experience working with lasers. The advanced laser technology creates highly controllable physical modifications on a surface of the materials. The process is eco-friendly and avoids using any form of chemicals instead relying solely on the precision of lasers.
Different colours are created by producing very fine nano-structures on the surface of metals, for example some colours are produced by tiny metal spheres formed on the surface of metal by laser pulses. The result is a mesmerizing, almost holographic effect on the keyrings surface, with colour brightness dynamically shifting based on the observer's perspective angle.
