This is a 3D keychain I bought during a trip to Taiwan. Purchased around 2018. It's a lenticular design, so the image changes when you move it. The front features dolphins underwater, and the back shows the Queen's Head at Yehliu Geopark. Keychain body: Diameter: Approximately 5.5cm Thickness: Approximately 0.5mm Ring: Diameter: Approximately 3cm There are fine scratches overall. There are several vertical scratches on the image on the back (see image 3). Please consider purchasing if you understand the condition.
