Conus levis exhibits a shell that can range from small to medium in size, typically around 9–12 mm in length. The shell is conical with a smooth surface and subtle spirals near the base. The coloration varies, but it generally displays shades of cream or light brown, often with darkerspots or bands, which serve as camouflage against sandy or coral reef environments. The snail's body is soft and encased within the shell, with a proboscis used for hunting prey.
