Cases may vary slightly in style and cosmetic condition

But function is good

I say "relatively compact" because it's slim enough to fit in a normal-sized backpack without too much drama

Kodak Polycontrast Filter Set brand_Whitehouse Products Inc. Pentax rolled the dice onThis is a complete Kodak Polycontrast filter set, with seven 3x3" mounted filters from grades 1 to 4 in half stop increments. Yes, these are compatible with Ilford Multigrade papers: they may not produce the exact same contrast as an equivalent grade Ilford filter, but they will definitely do the job. In very good cosmetic condition, with plastic case.
