I like these icons drawn in the “flat” style for user interface designs, though the fact that they’re in full-color and rendered fairly intricately probably makes them more suitable for illustrations within a product (e.g., onboarding screens) than as functional icons themselves. They’re also probably more at home in the context of Google’s Material Design aesthetic than Apple’s iOS 7/8 aesthetic. There are three sets available, each with one hundred pictograms, and each with a nice variety of the useful and humorous. Finally, they have a terrific name.

You can buy them here.
