These are new, old stock, 5x5 inch (125mm) Kodak filters unless specified otherwise. Big enough for your Aero Ektars, Aero Tessars, and other big glass. Relatively rare at this size; difficult to keep in stock. EX means no significant flaws. VG means mostly clean with no show-stoppers. G means useable but a bit rougher than one would like. Ready for action.  Same day shipping if ordered before 10am eastern time (US). Check out my MANY other Wratten filters in my store.
