replying to my own post...just want to mention that i was VERY PLEASED that POLARPRO included an EXTREMELY RUGGED ZIPPERED HARDCASE and 3 small silky smooth pouches in addition to the three nd filters (ND4, ND8, ND16). these accessories were not mentioned in the product description posted online. PLEASANTLY SURPRISED...THANK YOU POLAR PRO!
