A very easy to use toy base. Simply remove the pear link and fill with toy parts with a 3/8"+ hole or larger. There are 6" to 7" of 2.5mm chain, 1 3/4" o-ring (1" outside diameter), and a medium pear link with a wide opening. Made of nickel-plated zinc free steel. Recommended for medium birds or smaller. Can be used with large birds that play "gently" with their toys.
