A very slender italic serif with crisp, unbracketed slab-like terminals that read as thin, rectangular caps on many strokes. The design maintains a clean, even stroke feel with a gently drawn, monoline rhythm, while the italic angle and subtle curvature keep the texture lively rather than rigid. Capitals are narrow and elegant with simplified, open counters (notably in C, G, S), and several characters show tapered joins and slight entry/exit strokes that suggest pen-informed construction. Lowercase forms are smooth and readable, with a single-storey a and g, a modestly looped f, and a long, graceful descender on y; lining numerals are similarly light and open, with a distinctive, rounded 2 and a clean, oval 0.
Well-suited to editorial typography, book and magazine settings, and refined brand systems where a light italic voice is needed. It can also work effectively for invitations, packaging copy, and short display lines where its crisp slab terminals and elegant slant add character without heavy contrast.
The overall tone is poised and cultivated—more bookish and editorial than loud or decorative. Its airy hairline presence and steady italic slant convey sophistication and restraint, lending a quiet sense of formality suited to thoughtful, text-forward design.
The design appears intended to blend a disciplined slab-serif structure with an italic, pen-like cadence, producing a refined face that feels both classic and contemporary. It prioritizes elegance and readability through open shapes, restrained detailing, and a consistent, delicate stroke rhythm.
Serifs stay sharp and square rather than cupped or bracketed, creating a crisp edge at small details while preserving a soft, flowing baseline rhythm. The sample text shows consistent spacing and an even gray value for such a delicate style, with capitals providing a dignified, slightly calligraphic headline feel.
