Grows as a compact, structural, multi-ribbed sphere reaching roughly 4 to 6 cm in diameter at maturity.
The "Neon Braun" Effect: The body has a rich chocolate or burnt-sienna skin tone. When given proper lighting, the ribs develop a glowing translucent appearance at the top apex where the "neon" pigments are most highly concentrated.
Features 8 to 14 sharp, narrow ribs that are deeply etched with horizontal, band-like grooves between the areoles.
Carries very short, slightly curved, needle-like spines that sit tightly against the ribs, leaving the unique dark caramel coloration unobstructed.
