Four pockets offer a guarantee of security filters - no need to fear that they will rub on yourself. Pockets are made so that the filters were quite tight and not fall out. Internal side pockets are made of smooth, such that there is spreading and leaves no trace of the material. Foldable cover blocks access to the dust filters.
Be sure to brush or blow off any dust or loose particles on the lens before using the eraser head to remove smudges. The black powder on the eraser head is carbon and is meant to be there...don''t worry, it''s not ink and it''s not falling apart. Get one..works great!

If you have 52mm lens at your camera, it''s a cheap and very good accesory. Depend of what kind of photography you do. Buy it, it''s worth the bucks. Filter creates 8 pointed star of point objects of light
