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

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