VTG Studio Nova "scatter glass" Christmas tree and shooting star art glass piece

These miniature art glass "scatter glass" pieces are small enough to sit on a shelf but textured enough to catch the sun in a window. They are tiny little favors which will bring delight as grown up stocking stuffers. Are they candle holders? Maybe for a tiny little taper as they do have a little indentation on them. Are they candy dishes? No, they are solid. They seem to be created just to "scatter" around to bring smiles! Tree measures - 4 1/4 inches long x 3 inches wide. Star measures - 3 3/4 inches long x 2 1/4 wide. Pre owned, but in great condition with no chips, no cracks and no scratches. They labels are attached, but are very loose. Made in Italy.
