<p>Flex is all about the curves. Its smooth curves brings fluidity and dynamism to your designs with a modern appeal.&nbsp;The Neon style is especially effective in complex environments where&nbsp;quick recognition and hierarchy&nbsp;are essential. It also allows you to customize the line thickness.&nbsp;All Flex Neon icons are designed on a 14px grid with a 1px default stroke and two customizable line colors.</p>
