UV filter: Perfect for storing still on the lens to protect it from scratches (pro UV filter will allow better color accuracy made but will be more fragile).
CPL filter: Though to manage the effects of reflection or colors in very light conditions.
ND Filters: very good for you try to long exposures at this price hard to deprive yourself :)
Great deal with a storage bag.
The cover, however, is a bit cumbersome for departures on a trip, damage.
