Sizes vary widely. Listed heights include 16 inches, 11.5 inches, 9.5 inches, 7.5 inches and 5.88 inches. Some sets give dimensional ranges (for example about 8.66 x 3.94 inches down to about 5.51 x 2.56 inches).

Both battery power and AC/plug-in power are used. Some items are battery-operated (examples list 3 × AA or 3 × AAA), while others plug into a standard AC outlet.

Multi-piece sets commonly list multiple heights or dimensional variations. For example, one trio lists 7.5, 9.5 and 11.5 inches in height, while a mercury-glass package lists styles ranging from about 8.66 x 3.94 inches down to about 5.51 x 2.56 inches.

Some pieces offer lighting modes such as twinkling and steady LED settings; at least one listing mentions a built-in timer. Other items may have a single pre-lit setting.

Both formats appear. Many listings are single items ("Number of Pieces: 1"), while others are sold as multi-piece sets or multi-style packages (for example, sets of three or packages with multiple tree styles and crackle balls).
