it's free and easy to understand if you're already familiar with photoshop, illustrator, indesign, and XD. although, it's not really recommended to use figma for print bc it's meant for web only and indesign is still the standard.
there are a bunch of great figma plugins out there too that are also free to install. we mostly use figma for e-commerce prototyping/UX design and so far, we haven't encountered any problems sharing figma projects with clients.
