Eliot is Emalla's cartridge line. The round liner is for line work: outlines, contours and lettering. The needles sit in a round grouping, which keeps the line tight and closed. The long taper runs out gradually: a finer entry and less trauma to the skin.
0.30mm (bugpin) lays ink finer and a little slower — the diameter for detail, gradual build-up and work where control beats speed.
This family runs in 4 needle counts (3, 5, 7, 9). You order per box of 20 individually sterile packed cartridges; pick the needle count you need below.
