* While we strive to ensure that the photos are the same color as the actual product, there may be slight differences from the actual product due to the lighting conditions at the time of shooting, your monitor environment, etc. Also, some photos may be taken using a penlight.

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