Kwadron Curved Magnums
Kwadron Curved Magnum cartridges, also known as Soft Edge Magnums (SEM), are built for smooth colour fills, shading and blending. The curved needle grouping produces a natural haze, more intense in the centre and softer on the edges, which makes gradients and realistic work easier to control. A staple for professional tattoo artists, in black and grey as well as colour.

Once the outline is done, artists switch to a curved magnum: fine 0.25 mm groupings for delicate transitions, 0.30 and 0.35 mm for colour packing and large shaded areas, Medium Taper when saturation matters more than softness. Sublime is the choice for seamless colour blends, Combat for backgrounds and large coverage. Pick the diameter and needle count that match the surface you are covering.
