A monospaced slab serif with sturdy, squared proportions and prominent, mostly bracketed serifs that read clearly at text sizes. Strokes are largely even with subtle modulation, giving the forms a firm, mechanical rhythm. The lowercase shows a two-storey “a” and single-storey “g,” open apertures, and compact, workmanlike curves; terminals are blunt and rectangular. Figures are straightforward and tabular in feel, matching the gridlike spacing and reinforcing a consistent, typewriter-like cadence.

Well suited to contexts where fixed-width alignment matters, such as code samples, terminal-like UI, tables, forms, and structured technical documentation. It also fits retro office aesthetics for posters, covers, or captions where a typewritten voice is desired.

The tone is practical and matter-of-fact, evoking typed documents, technical notes, and institutional print. Its strong slabs and steady spacing add a dependable, slightly retro character that feels familiar and archival without becoming ornate.

The design appears intended to combine typewriter-style monospacing with robust slab serifs for legible, dependable text in structured layouts. Its restrained detailing and consistent rhythm suggest an emphasis on clarity, alignment, and a classic documentary feel.

The design maintains a consistent color across lines, with clear differentiation between similar forms (e.g., I/l/1 and O/0) aided by serifs and distinct shapes. The heavy serif presence gives it a confident footprint in short text while keeping counters and joins relatively open for readability.
