The mark consists of the stylized wording "SISTERBIRD" curved inside the bottom of a double circle with a thicker line for the outer circle. Above the literal element "SISTERBIRD" is a solid circle cut in half by a branch with a bird on top, and five equally spaced flowers curved inside the top of the double circle. The double circle design element overlaps on top of a long solid rectangle with two thin border lines inside.
