I was browsing the web when one site led me to another and I landed on the website of ArtBox7. It is a commercial site that sells graphics but it also runs giveaways sometimes through other art and design blogs and websites.

Stefan, the owner, also encourage readers to sign up to the newsletter where a monthly winner will be selected to win a supreme graphic set worth US$99.99. The winner has the freedom to choose his preferred prize.

I think that winners of the “Supreme Set” can use the graphics on commercial sites even though it is free since it is a prize. Anyway, if you are lucky enough to win, check with Stefan. Good luck!
