※ While we strive to ensure product photos accurately represent the actual color, there may be slight differences due to lighting conditions during photography or your monitor environment. Additionally, some photos may have been taken using a penlight.

※ For products with UV fluorescence photos, we use a 365nm wavelength black light. If you use a light with a different wavelength (e.g., around 395nm), the fluorescence may appear weak or be difficult to confirm. The black light we use is available here.
