Adorama 120 Size Slide Storage Box with Dividers, Holds 180 Slides, 18 5/8x3 5/16x3 1/16"

Master unit slide storage boxes contain six boxes within a box and store up to 2,160 slides in easily identifiable groups. Available in sizes for 35mm and 2 1/4" square mounted transparencies. Each inner box (slide tray) will hold up to 360 slides. 35mm boxes come with neutral pH, non-buffered alpha cellulose index tabs to separate slides into eighteen groups; 120mm boxes have tabs for thirty compartments. These boxes also feature our follower block system, which prevents slides from shifting in partially filled boxes. Full depth lids add extra protection, strength, and security
