Sold a bunch of these 10X12 inch sheets of Lithographers Red Rubylith sheets to use as filters for computer monitors to preserve your dark adapted eyes at night. Also, suitable for covering tubular lighting in darkrooms or where ever you need to see red. Transmission is comparable to a #25 photographic filter.

Have a small stack left and will sell 2 sheets for $5 postpaid in CONUS.
