These boxes are designed clamshell-style, with integral, folding lids which offer convenient access when inserting or removing negatives, prints, or glass plates. They are to be used with four flap negative enclosures (conventional negative envelopes will not fit). This creates a two-part system for the safe, long-term storage of negatives, prints, or glass plates. The individually wrapped item fits snugly in a box sized to provide a precise fit. Sized for 5 x 7 or 8 x 10 material.
