Kwadron Classic Liners
Kwadron Classic Liners are traditional on-bar tattoo needles for artists who prefer the feel and control of a conventional needle bar over cartridges. Each grouping is precision-soldered in a Round Liner Long Taper (RLLT) configuration for sharp, clean lines, pass after pass.
What you get
- Box of 50 needles on bar
- Two needle diameters: 0.30 mm and 0.35 mm
- Five groupings: 3, 5, 7, 9 and 11 needles
- Round Liner Long Taper (RLLT) configuration
- Stainless steel, EO gas sterilized
- Reading the options: 0.30 or 0.35 is the needle diameter in mm, LT means Long Taper, and the Needles value is the number of needles in the grouping
Round liners are the standard choice for outlines, lettering and fine detail. A 3 or 5 handles delicate linework and small script, while a 7, 9 or 11 lays down bolder outlines in fewer passes. The long taper gives a more gradual point that many artists prefer for controlled, precise line placement. Choose 0.30 mm for finer lines or 0.35 mm for a slightly bolder line with the same grouping, and run these needles with the tubes and grips you already use for on-bar work.
