An exemplary system is provided for holding storage goods, and generally includes a first tray and a second tray. The first tray includes a plurality of first wells, a first engagement pattern, and a first long axis, and the first engagement pattern is formed at least in part on one or more of the first wells. The second tray includes a plurality of second wells, a second engagement pattern, and a second long axis, and the second engagement pattern is formed at least in part on one or more of the second wells. The first engagement pattern and the second engagement pattern are configured to engage one another to thereby discourage relative shifting of the first tray and the second tray. With the first engagement pattern and the second engagement pattern engaged with one another, the first long axis and the second long axis extend transverse to one another.

An open container, in particular a plastic container, for transporting and displaying goods. The open container has a bottom, a rear wall protruding from the bottom, two opposite side walls protruding from the bottom, and a front wall provided with a cutout or a completely open end side. The open container can be mated with a further, identical container turned upside down to form a closed container. The side walls have side wall portions that may be trapezoidal or crenellated. The side wall portions are offset to each other laterally or in the transverse direction of the wall and overlap with corresponding side wall portions of the identical, upside-down container, preferably over the entire height of the side wall portions, and are fitted together.

A pet fountain comprises an upper bowl, a base including a lower bowl. The upper bowl can be secured to the base so that it is elevated above the level of the base.
