A compact slab-serif with square, blocky serifs and a subtly irregular, hand-set rhythm. Strokes stay fairly even, with crisp, flat terminals and small wedge-like joins that give many letters a lightly notched, inked feel. Capitals are narrow and tall, while lowercase forms are simple and utilitarian, with single-storey a and g and a narrow, slightly curved f. Numerals are similarly compact and open, maintaining the same sturdy serif treatment and consistent texture across lines of text.
Works well for editorial settings where you want a classic, print-forward texture—pull quotes, headings, and short-to-medium passages in books or magazines. The distinctive slab details also suit packaging, café menus, and poster copy where a vintage, typographic voice is desirable.
The overall tone reads like an old typewriter or letterpress impression—practical and literary, but with a bit of eccentric charm. Its slight unevenness adds warmth and personality without tipping into overt script or handwriting.
Likely intended to evoke traditional typesetting and typewriter-era serif forms while remaining compact and readable. The square serif construction and slightly roughened detailing appear aimed at delivering a sturdy, characterful text face for display and editorial use.
The design favors clear verticals and tight sidebearings, producing a dense, rhythmic color in paragraphs. Several letters show small asymmetries and sharp interior corners that enhance the analog, printed character.
