I can't remember where I heard of this thingy, but I know that it's originally made by Goody. I've never seen this kind of hair accessories here in Slovenia, so I searched for it on Ebay. Of course. =) I found the original Goody pins, but I'd had to pay 6 € for two pins. I looked some more and found the non original pins. They looked the same to me, so I bought them ... for 1 € (two pins, postage included). Here's what they look like. I can now see that these (non original ones) don't have the protective ''cap'' on the ends. The edges are actually quite sharp, but it's nothing that can't be fixed with a simple nail file. ;)
I have to admit I was sceptic at first. But then I tried it and I was simply amazed. This thing works! Look at my not-so-small-or-messy bun. I only used the two spin pins from the photo above.
Here's one for my nail polish junkies. To get the idea of size of spin pins (next to China Glaze Japanese Koi).
As I already said, you can get original or ''fake'' spin pins on Ebay. You'll have to decide which one you'll buy, but in my humble opinion - there's no need to pay 6 times more for the Goody ones. Just sayin'!
EDIT: I totally forgot to tell you how this thing works. Well, this is how: you gather your hair into a pony tail (with your hands only), twist your hair around the base of the ponytail into a bun. Take your first spin pin and insert it by twisting it clockwise. Take your second spin pin and insert it like the first one and that's it. You're all done. =)
Thanks for looking!
