FC rings come in a range of sizes and prices as in the size table below.

For birds smaller than cockatiels the plastic split rings are a slightly different design, going aroiund the leg only once and relying on the strength of the plastic to act as a spring to hold the ring in shape. However, as the rings get bigger they need to go around the leg more than once to increase their strength – in a flat coil, as shown in the photograph.

Numbered FC rings are usually made to order so a two to three week order period is often required.
