Jumbo size pear head pins?

I didn't know where to post this but thought I'd start here.I am looking for a source for pear head pins that are 3 1/4" long with a 3/8" head. My grandmother used to get them from Lee Wards but I have not been able to find this size at Michael's (who I understand bought Lee Wards), Hobby Lobby, Hancock Fabrics, Walmart or even on the internet.

I'm totally new at crafts so I'm not familiar with the good sources that might not come up on google.Can anybody suggest a site I might look at for these?
Thanks,
Sherry
