Yep! Once you own the pack, these icons are commercial a-okay for whatever you wanna do!
(Except for reselling them on their own, obviously.)
Sweet, thank you! Do you announce anywhere when/if commissions open too?
Sadly I'm shutting commissions for the foreseeable future since I've got some pretty big, long-term jobs on the go, but keep an eye on my Twitter (@cazwolf) in case they ever open back up again! <3
