Hoya Digital Filter Kit II (37mm) contains:

• HMC Ultraviolet (UV) Filter - helps protect your cameras from dust, moisture and scratches.
• Circular Polarizing Filter (double coated) - dramatically deepens blue skies, reduces unwanted 
  reflections on nonmetallic surfaces and saturates colors, especially outdoors. The filter can be rotated
  to achieve the desired effect.
• NDx8 Neutral Density Filter (double coated) - Neutral Density filters have several uses and offer the possibility to achieve otherwise unachievable results. ND filters appear gray and reduce the amount of light reaching the film or sensor. They have no effect on color balance.
• Nylon Filter Pouch
• Filter Guidebook
