The last link in the end of this chain has a slightly larger ID than interior links and will fit a 23ga jump ring.  This is a tiny link so you may require magnification and steady hands for finishing.

Footage Chain Note: Bulk chain is priced per inch. All chains are sold by the inch unless a 10 foot minimum is noted. Spooled chains sometimes have spliced lengths from the factory so we cannot guarantee continuous lengths of any specific measure. Cut chain shorter than 12 inches cannot be returned.
