A delicate outlined serif with a consistent double-line construction that creates an airy, hollow letterform. Strokes read as monoline outlines with rounded corners and small bracketed serifs, giving the forms a gently engineered, ornamental feel. Curves are smooth and open, counters are generous, and the overall rhythm is even, with clear separation between the outer contour and the inner inline across both uppercase and lowercase. Numerals and punctuation follow the same outline logic, keeping a cohesive, light-on-ink texture at larger sizes.
Best suited to headlines, short phrases, and brand moments where an airy outlined serif can add character without visual heaviness. It can work for packaging, signage, invitations, and editorial pull quotes, particularly in larger sizes where the double-line detail stays crisp.
The tone feels vintage and lightly whimsical, like turn-of-the-century titling or engraved stationery interpreted in a clean, modern vector style. Its openness and fine outlines give it a refined, slightly playful character rather than a formal, weighty one.
The design intention appears to be a classic serif voice translated into an outline treatment, emphasizing lightness, ornament, and a crafted look while keeping letterforms familiar and broadly readable.
The outline-only construction makes interior detail a primary feature, so the design reads best when there is enough size and contrast to preserve the thin contours. The lowercase keeps a straightforward, readable structure while still carrying the same decorative outlining, helping longer sample text remain orderly despite the display styling.
