Any feather experts?

I want to have this hair comb custom made.  Does anyone know what kind of feathers these are?

I am not sure, but I know that people have bought similar things from Etsy.  Perhaps if you choose a vendor and send them the picture, they could help you.  Sorry I can't help more.

Thanks Pink, I've already posted it on Etsy but one person came back to me and said they would use marabou feathers which I'm pretty sure they are not.  I've seen marabou feather boas and they don't look like these.  So I was just wondering if someone might know what they are. 

I believe those are non-stripped coque feathers.  I have a bag right next to me.  Yes, I'm a nerd.

Yes! I googled them and you're absolutely right. Thank you so much and by the way, you're not a nerd.  :-)
