B Kaj by Borna Rayaneh is a free Arabic 3D display font defined by tall angular lettering and long black shadow wedges that push each form forward. The repeated diagonal depth gives the design a hard poster-like rhythm, so the font reads less like ordinary display type and more like carved signage translated into sharp graphic planes.
That strong shadow structure makes B Kaj a natural choice for event posters, album art, gaming graphics, packaging, and storefront branding, where the free font can give short text a sense of depth without extra effects. It has enough presence for headlines, title cards, and cover lines, especially when you want a few words to carry the whole layout.
