This solid black thick silk streamer instantly changes to red, yellow, green & blue squares, reminding me of Rubik’s Cube. Size is about 6” wide x 4 feet long. Works exactly like the Shake Silk (Color Changing Streamer), turning inside out from black to colors, or from colors to solid black. This is made of a heavier silk (about 8 mm) so there is no see-thru of colors through the black fabric. Supply limited. Very well made.
