Genuine Rosco #7300 linear polarising film, full 43 × 50 cm sheet. The axis of polarisation runs parallel to the 43 cm (17") side.
Seconds: fully functional, polarisation tested. Rippled from long storage, so best for lighting, small cut pieces, cross-polarised photography and school demos. Not suitable where a perfectly flat sheet is needed.
Limited clearance stock, sold as-is.
