Comments about Pro-Line Adorama / Pro-Line Individual 35mm Slide Protector Sleeves for 2x2 Mounted Transparencies, Clear Both Sides, Box of 100.:
The sleeves are a little smaller than the cardboard mounted slides. It takes some effort to slip the sleeve over the slide. sleeve is open on 2 sides. It would be better if it was open on 1 side only ( like an envelope ).
There is nothing better out there, so I have to live with it!
