※ While we strive to make photos appear as true to life as possible, there may be slight differences from the actual product due to lighting conditions during photography or your monitor environment. Some photos may also be taken using a pen light.

※ For products with UV fluorescence photos, the photos are taken using 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 here.
