This is the demo, bare bones, version of Knucklebones. It is free for personal use ONLY. If you are going to use it commercially, buy the full version, which comes with kerning, embedding rights, all glyphs (including the 4 & 5) and extras from my site: hanodedfonts.com. You CANNOT use this font in games, apps, or software. If you want a license for that, buy one from my site www.hanodedfonts.com
or read the FAQ file included in the zip.
