This a wonderful item that can be produced from a hat or other production apparatus. The metal cage mesures about 5" x 5" x 6" tall. When collapsed however, it is only 5" x5" x 2" tall, and there is still room for a live or rubber canary! The cage expands simply by grabbing the cage by the handle on top. As it is lifted, the cage automatically expands! The cage is made out of nickle plated brass and the craftsmanship is exquisite. These cages are hard to find and we only have a couple left in stock. 001CBMPRODBIRDCAGE
