Perma/Dur Barrier Board Document Cases, Black
PermaDur Barrier Board Document Cases Black
An attractive alternative, our black boxes are made from a sturdy 60 pt. acid-free scuff resistant board and buffered with a 3% calcium carbonate, suppressing the migrant acidity that comes through handling and environmental sources. The interior is lined with white paper and measures a pH of approximately 8.5. The metal edge we use to construct our boxes offers more "grips" per inch than many other manufacturers, creating a stronger, more durable box. Larger (5") boxes feature a black nylon cord loop that allows easier removal from shelving.
