A compact, heavy slab serif with broad, blocklike construction and squared terminals. The letterforms are built from thick verticals and rounded bowls, then punctuated by consistent internal notches and wedge-like cut-ins that read as deliberate “bites” from the strokes. Counters are generally small and simplified, and the overall texture is dense, with tight apertures and strong silhouette-based differentiation. The serifs are sturdy and rectangular, with a mostly even stroke presence and slight shaping where cuts interrupt joins and bowls.
Best suited to display settings where the heavy color and notched details can be appreciated—posters, big headlines, branding marks, and packaging. It can also work for short, energetic copy in advertising or event materials, but its dense forms and tight openings make it less ideal for long text or small sizes.
The notched detailing and oversized weight give the font a punchy, mischievous tone that feels both vintage and novelty-driven. Its rhythmic cut-ins add movement and character, pushing it toward expressive display work rather than quiet utility.
The design appears intended to deliver maximum impact with a recognizable signature detail: bold slabs paired with consistent internal cut-ins that create a stylized, almost stencil-like personality. The goal seems to be high visibility and a memorable, slightly cheeky texture for statement typography.
The distinctive cut-out motif appears across caps, lowercase, and figures, creating a unified visual gimmick that becomes more apparent at larger sizes. Numerals share the same heavy, simplified construction, and rounded characters (like O/0) remain strongly black with tight inner spaces, reinforcing the poster-like color.
