Igra Studios

We develop casual games and game-related assets.

All assets have the same license as on Unity Asset Store. That is, you can use a purchased asset in any number of games (e.g. dress-ups, visual novels), books, videos, websites, marketing materials or any other products of yours, including commercial. No attribution required.

Basically, the only thing you can't do is re-sell the asset as your own on this or other asset stores, even as part of of a bigger package, even with minor modifications or even mixed with other assets of which you're the author.
