What about your CC license fonts (Arsenale, Partigiano)?
Some of our fonts are distribuited as "free fonts" according to a "creative commons - attribution" license. That means that you can use them freely in your projects, both commercial and noncommercial, as long as you can provide attribution.
For example, if you're using Arsenale white for a project you have to put in the credits page, colophon, or credits line - the author indication: " font [arsenale white] by studiokmzero and happyloverstown".
If you can't for whatever reason use the fonts with attribution, you can still use your fonts freely in noncommercial work - but if you want to use our CC fonts for a commercial - non credited work you have to buy the standard license for them - contact us for information.
