The 81 series filters, formerly used for light balancing with film, now are used for their delicate warming effects. Great for pictorial and portrait shooting. These are new, sealed, old stock, unless otherwise denoted. EX= no or very minor flaws. VG= still nice but with more marking. FYI- Calumet frames are made of adhesive card stock permanently attached to the filter. Free domestic shipping and low cost international shipping in a hand addressed envelope. (Tracked shipping available- select the higher cost shipping option.) Same day shipping if ordered before 10am eastern time (US). Check out my other Wratten filters in my store. Also filter frames and filter holders are available.
