These boxes are made with our white archival corrugated board which meets the ISO 14523 Standard. Both boxes fit well on standard storage shelves. The 23.75" long box fits on 24" shelves, and the 15" long box fits two deep on 30" and 36" shelves. Both boxes come with 6 piece partitions with extra slots which can be used to divide the box into numerous different compartmental configurations. The boxes have hand holes in the bottom ends for ease of use. The hand holes are only in the outer panel of the double panel ends so the inside of the box is not exposed to the openings. 23.75" Long x 12.5" Wide x 6.25" High - Artifacts Box & Partitions $25.60, 3/$73.05, 6/$139.20, 12/$265.20, 24/$495.60 15" Long x 12.5" Wide x 6.25" High - Artifacts Box with Partition $20.70, 3/$59.10, 6/$113.40, 12/$214.80, 24/$409.20
