These sturdy Pop-Up Slide Holders hold 20 standard 76 x 25mm (3 x 1") slides in compartments numbered to correspond to the printed index on the cover. The compartments are recessed so the specimens can't be touched when the covers are closed. Slides pop-up with a slight pressure at one end. Each holder is made of heavy pressed cardboard with a white finish. Hinged covers are attached with durable black tape.
The 20 slide holders are available in five different coloured tape for easy sorting and storing. Closed dimensions: 203 x 343 x 96mm (8 x 13.5 x 0.38")
