These have been darkroom stored and are expired. I can't guarantee results, but I have had excellent results from darkroom papers well past date. 

All are surface F2. One 25 pack and two 100 packs. The 25 pack is sealed, NOS. The single weight 100 pack appears to be sealed and feels full, but it's possible it was opened with just a few sheets used. The other 100 pack is a nice double weight paper and feels to be around half full. 

As a rough estimate, I would say there are at least 175 sheets here, possibly more.

Thanks for looking!
