COP  Clip On Peepers
$4.30
Clip on Blinders are a little bigger than the economy blinders. Come with a built in pin, can bend forward and then sit the pin in the nostril and you are done. You can use the plier to make it easier to apply them. Order that separately. Birds need to be at least four weeks before applying them. For some of us this will be easier to apply because the pin doesn't go all the way through the nostril.
