This is an Eye of Agamotto necklace sold by SalesOne. It is an authentic product. After purchase, I checked the contents and then stored it in a box in a dark place. The retail price is 11,000 yen. This is the light-up version, and the Time Stone part glows green. There are no issues with the operation, but the box was already quite damaged at the time of purchase. Please feel free to ask any questions in the comments. Doctor Strange Avengers Infinity Stone MARVEL MCU
