Eliot is Emalla's cartridge line. The curved magnum has a curved needle row: only the centre reaches the deepest, so the edges taper out softly. That gives smooth transitions in shading and larger areas, with less trauma at the edges. The long taper runs out gradually: a finer entry and less trauma to the skin.
0.35mm is the standard diameter: a bit more ink per pass, so you cover larger pieces faster.
This family runs in 6 needle counts (7, 9, 11, 13, 15, 17). You order per box of 20 individually sterile packed cartridges; pick the needle count you need below.
