Hi Cold,
I've never bought them online, but here's what I found doing a google search on black magic hooks online
http://www.blackmagic.co.nz/catalogue/freshwater.php
this should take you to a page with 2 links as the hooks are divided over two pages.
These hooks are silver (stainless), though they look black in this image, and have very small barbs. I like the A series for wee wets, and E series for dries.
As I say, I've never used their online ordering before, but it's worth looking at.
