Originating in Austria, the Kaiser roll is easily identified by the star pattern on top (which looks particularly nice when illuminated.. and brings to mind the Kaiser's crown). Because only real rolls are used to make this lamp, variations will be seen piece to piece. Approx 3.5"x 3.5"x2"
materials: Strong flour, weak flour, yeast, LED lights, battery, etc.
