ABSTRACT OF THE DISCLOSURE A cassette for holding a stack of cards, paper or the like sheets to protect the stack and to enable removal of one more sheets or of the entire stack. The cassette is of an extremely simple and thus inexpensive, unitary, flat struc- ture having a bottom wall, peripheral walls for protecting the edges of structural sheets and a spring tongue on top, the spring tongue being unitary with the rest of the structure. The spring resiliently urges the stack against the bottom wall. The bottom wall has an opening for pressing the stack within the cassette against the spring when removing one or several of the sheets. The advance over prior art is not only in an inexpensive structure but also in convenient handling of the sheets, whether in re-filling or in removal of the entire stack or of only few sheets, as the spring tongue is maintained in contact with the stack during the removal of the sheets thus preventing accidental spilling of the cards or the like.
