For $1 more, add a tie-tack connector and wear it together with one of your pony ties (Or even a non-pony tie, if you so wish...)!
The pins are fairly small and do present a choking hazard. Keep out of the reach of children, pets and baby dragons. Do not swallow pins. Connector on back of pin is sharp, don't poke yourself or anyone else with it. Consult a specialist if swallowed. No, you still don't get my quarter
