We started with 3mm chain and a softball size whiffle ball. Then using 1/4" cotton rope, we added 4 giant fish, large interstar rings, 2" plastic chain, 1 1/2" wood wheels, 1 1/4" wood beads, and 2 1/2" square wood blocks to create this fun toy. Comes in assorted colors and measure apx. 9 1/2" wide by 17 inches long from the top o'ring. 5 mm np quicklink included.
