※ We strive to ensure that the photos represent the actual colors, but they may appear slightly different depending on the lighting conditions during photography or your monitor settings. Some photos may also be taken using a penlight.

※ For products that include UV fluorescence photos, they 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 weaker or be difficult to confirm. The black light we use at our store is here.
