A hairline, condensed slab serif with tall proportions and minimal modulation. Strokes are consistently thin, with small, square-ended slab terminals that read as crisp and unbracketed rather than flowing. The rhythm is vertical and columnar, with generous internal whitespace and a slightly calligraphic irregularity to some curves and joins that keeps it from feeling purely mechanical. Numerals and capitals follow the same narrow, elongated build, giving lines of text a light, spidery texture.
Best suited to display work where its airy texture and tall letterforms can be appreciated—headlines, poster titling, packaging labels, and editorial pull quotes. It can also work for invitations or branding accents when used at larger sizes with comfortable spacing.
The overall tone feels delicate and cultivated, with a hint of eccentric charm. Its tall, whisper-thin strokes and neat slabs evoke vintage display typography—quietly elegant, slightly offbeat, and more about atmosphere than forceful emphasis.
This design appears intended to deliver a refined, ultra-light slab-serif voice in a condensed silhouette, balancing crisp rectangular terminals with gently idiosyncratic curves. The goal seems to be a distinctive, vintage-leaning display presence that stays elegant and understated rather than heavy or blocky.
At text sizes the thin strokes create a pale color and emphasize spacing and silhouette over stroke detail. In samples, the narrow set and pronounced verticality produce a distinctive, elongated wordshape that can feel theatrical in headlines but restrained in short passages.
