Christmas Tree Jingle - a cute holiday stainless toy with 3 Christmas trees, some beads, a splash of red beads, 2.0mm orings, 1.6mm chain. The large tree size is 2-3/4" tall and the two smaller tree size is 1-1/2" tall. This toy would be good from small to medium bird sizes, any bird larger than medium size, the orings on this toy most likely will not hold up to the large Macaws or Cockatoos unless they are gentle toy players!
