A quirky, typewriter-adjacent serif with compact proportions and a consistent, single-width rhythm. Strokes are sturdy and fairly even, with soft, slightly blobby terminals and subtle irregularities that feel stamped rather than drawn with strict geometry. Serifs read as slab-like and rounded, and many glyphs show small notches and waviness that mimic uneven inking. A distinctive built-in underline appears as a separate bar beneath each character, creating a strong baseline band across words and lines.
Works best for short display settings where the underline can be treated as a deliberate graphic feature—posters, book or film titles, zines, labels, and playful packaging. It can also be effective for novelty UI labels or badges, but extended reading and small sizes may feel busy due to the constant underline and textured edges.
The overall tone is playful and offbeat, with a nostalgic, analog personality. Its uneven edges and persistent underlining give it a mischievous, tongue-in-cheek voice—part vintage office ephemera, part handmade oddity—well suited to humorous or intentionally imperfect messaging.
Designed to evoke a stamped/typewritten look while pushing it into a deliberately odd, decorative direction through softened serifs, uneven contours, and a per-glyph underline. The goal appears to be instant personality and visual punch rather than typographic neutrality.
The built-in underline is the dominant stylistic device: it increases visual density and creates continuous horizontal texture that can overpower tight leading or dense layouts. Letterforms remain recognizable, but the underline and irregular inking effects make the font feel more like a graphic treatment than a neutral text face.
