Investigated for my new camera system some filters; even to protect the lens and on the other hand for some effect photos. Came to this filter set and am very satisfied. Packaging in the bag is ok. The filter thread is wipe (screwing) with a soft cloth before first use because it could small iron filings from the production may still be present. Thus, a possible damage of the thread to the camera is avoided. For my purposes, this product of Polaroid is sufficient. The processing of the filter is very good, and the thread is a perfect fit.
