The wings of butterflies, so to speak, have been captured in a small glass world. The blue color is not due to the pigment of the butterfly's wings themselves, but rather the way light interacts with the microscopic structures of the wings. It's not just a single shade of blue; depending on the angle of the light, you can enjoy various expressions, from pale purple and greenish colors to a light amber. Therefore, it sparkles and makes its presence known even indoors, in the shade, or on cloudy days by receiving subtle light. How about a beautiful, science-inspired decorative item? The wings used are natural, real specimens. Please remove it when bathing, and avoid using it in places with high temperatures and humidity. The photos were taken near a window with natural light. Due to the characteristics of structural coloration, the color impression may differ from the actual product depending on the brightness, angle of the photo, and the device you are viewing it on. Please understand this.
