A set of pixel perfect, filled icons for mobile functions (a lot of them)! If increasing size, always do it with even numbers, so they stay pixel perfect. Do the same for stroke weight. They are in a 64x64px artboard with 2px line weight, so increase size to 128x128px, 256x256px, stroke weight to 4px, 8px, and so on. You can use them for commercial use.
