A very condensed, tall display face built from slender, monoline strokes with an internal inline that creates a hollow, double-stroked effect. Forms are mostly geometric and upright, with rounded corners and squared terminals that keep counters narrow and vertical. Curves are simplified into tight radii, and several glyphs show subtle irregularities in the inline that read as intentional, giving the outlines a hand-drawn, technical feel. Spacing and widths vary by glyph, but the overall rhythm stays consistently narrow and vertical.
Best suited for display applications where its condensed silhouette and hollow inline can be appreciated—posters, headlines, signage, and branding marks. It can also work well on packaging or labels that benefit from a retro industrial tone, especially when set with generous tracking and ample size.
The inline hollow construction evokes vintage signage and Art Deco-era titling, with a sleek, engineered character. It also carries a light “neon tube” or instrument-panel vibe, making it feel retro-futuristic rather than purely historical. The slight wobble in the inner line adds personality and a crafted edge, keeping the mood from feeling sterile.
The font appears designed to deliver a compact, space-saving display voice with a distinctive hollow/inline construction, echoing vintage sign lettering while staying clean and geometric. Its narrow proportions and consistent vertical stress suggest an intent to create impactful titling that remains legible while looking decorative and engineered.
The design emphasizes verticality: ascenders, capitals, and numerals sit tall while bowls and crossbars remain compact, which reinforces a poster-style presence. The hollow/inline treatment is strong enough to read at display sizes, but the thin strokes and interior detailing suggest avoiding very small sizes or low-contrast backgrounds where the inline may fill in.
