A long, thin tube shaped box that can be opened from either end. You'll find hundreds of different models of these at the local supermarket. It is used as a medication box, for packing bottles of perfume and of course for playing cards. The default dimensions are fine for a set of standard, European, playing cards (“bridge size”).
TheMaterial Thicknessis only used for the geometry of the tuck flap.
(Poker sized playing card measure 2.5×3.5 inch, by the way.)
