The Round Liner Long Taper in 0.30mm (#10) is the most used liner size and the workhorse in many studios. Ink flow is even and controlled: fine enough for detail, yet less restricted than the tighter soldered 0.25mm. That makes this configuration usable in almost any style or technique, from fine linework to solid outlining. Cartridges in this size are sometimes called double zeros, after the notation in which 10 marks the needle diameter.
The long taper forms a gradual point that cuts clean lines without overworking the skin, so you get sharp contours with less trauma and calmer healing. Kwadron's needle stabilisation system and medical grade plastic housing keep the needle group stiff and focused through long sessions, which is why this size is a lasting bestseller in the Kwadron range.
Each box holds 20 individually sterile packed cartridges, and every cartridge carries the original Kwadron code so you can grab the right configuration at a glance.
