A parallelogram shaped box with side walls formed by parallel, generally rectangular bar members has a plurality of grommets inserted into the side walls between the bar members. Each grommet is trapped between adjacent bar members by clamping of adjacent bar members. Each grommet has a thickness greater than the thickness of the bar members and has a boss in the grommet with a pin retainer in the grommet, such as a straight hole. A pin placed in the pin retainer can support a decorative article so that external sides of the box can be decorated.
