This is Good Smile Racing's <MSS-29> Color Decal (Glow-in-the-dark) (Silkscreen Printed) It will glow for a short time when moved from a bright place to a dark place, or when the room lights are dimmed. Although it consists of numbers, circles, and squares, by cutting them out with a design knife or similar tool, they can be used for the camera and sensor parts of Gunpla. Since they do not glow constantly, they are effective for things like taking photos of your creations. Thank you for your consideration.
