A very thin, hairline slab serif with square, unbracketed terminals and a clean, measured rhythm. Strokes are consistently light, with restrained contrast and crisp joins that keep the outlines feeling precise rather than calligraphic. Proportions are balanced with a moderate x-height, open counters, and carefully controlled curves; the slabs are small but distinct, giving structure without adding visual weight. Numerals and capitals maintain the same airy, linear color as the lowercase, producing a quiet, high-resolution texture in text.
Best suited to editorial headlines, fashion and beauty branding, and upscale marketing where a delicate serif voice is desired. It can work for short passages or pull quotes when set large with comfortable leading, and it also fits refined stationery and invitation work where a crisp, minimalist serif is appropriate.
The overall tone is refined and contemporary, with a fashion-forward elegance that reads as calm and deliberate. Its extreme lightness and sharp slabs lend a poised, gallery-like atmosphere—minimal, clean, and slightly formal.
The design appears intended to combine the structural clarity of a slab serif with an ultra-light, modern presentation. It emphasizes precision, restraint, and a premium feel, delivering serif cues without heaviness and maintaining a consistently airy texture across cases and numerals.
Because the hairline strokes and small slabs are so fine, the face relies on generous spacing and benefits from larger sizes or high-contrast output contexts. In continuous text it creates a pale, sophisticated typographic color, with punctuation and dots appearing intentionally understated.
