※ While we strive to ensure that the colors in our photos match the actual items, they may appear slightly different depending on lighting conditions during photography or your monitor settings. Some photos may also be taken using a penlight.

※ For products featuring UV fluorescence photos, these are taken using a 365nm wavelength blacklight. If you use a light with a different wavelength (e.g., around 395nm), the fluorescence may appear weaker or be difficult to confirm. The blacklight used by our shop can be found here.
