Appears to be new in open box. Contains six filters and an adapter for 3" enlargers. The filters are in plastic sleeves, open at one end. Note that the filters are made of a soft plastic-like material and have become a little wavy over time. You should be able to correct this simply by pressing them under a heavy book or other flat object for a time until they 'remember' they should be flat. Otherwise, they appear to be in great, usable shape.

Polycontrast Filter Set

Full 7 piece set (six filters, one adapter)

Adaptor for 3" enlargers

For use with All-Color Drawer Enlargers using up to 3" filters

"The user of polycontrast or multigrade papers will assist the photographer in the darkroom by eliminating the need of several grades of paper."

Please examine photos carefully. I do not have an enlarger and have not used this type of filter before.
