all of those were made exclusively for NS by me, so they are 100% original. I had released a number of these a while back.. but my site went down like 2 years ago and I never brought these back.. Until now.
Some members might still be using a few of these icons.. so it's possible someone else has it.. and these have ended up on a few different forums/board across the web.
but I can assure you that the majority of these are still up for grabs and HAVEN'T been used yet.
and there's quite a few in there that are brand spanking new
so feel free to use them however you want!
