Premium license
You don't need to attribute to us and can use the assets you download forever. You can use them in any type of project: templates, website design, application design… even logos as long as you respect the 100 icons per project and 50 illustrations per project limit. A company can have multiple projects! You can also purchase discounted seats to license your team.
