Jelly Beans Bright and colorful jelly beans against a black background make this a fun spring collar. The high quality cotton fabric is sewn against a polypro base that is first completely wrapped in black cuddle satin to really bring out the bright colors of the jelly beans and for soft comfort for even the most sensitive of necks.
