A beautiful collector-quality specimen of Casmaria erinaceus, displaying a gorgeous creamy white body accented by distinctive dark brown rectangular markings along the outer lip and shoulder. The striking contrast between its glossy white surface and rich brown markings gives this specimen excellent visual appeal.

This attractive helmet shell features a rounded, inflated body, a well-developed stepped spire, and a beautifully formed aperture. The exterior has a smooth, highly polished appearance with subtle lavender tones, while the aperture reveals a rich golden-brown interior surrounded by a thick, glossy white outer lip.

Measuring 34.64 mm, this is a lovely example of the species with excellent natural coloration and attractive overall presentation.

Collected by a local fisherman while diving at depths of 3–5 meters near Nias Island, Indonesia.
