All Mithra 8-Gauge Bugpin Needles fit one size down when pairing with tubes.

Example: 7 Magnum Bugpin needles will fit into a 5 Magnum tube; 9 Magnum Bugpin needles will fit into a 7 Magnum tube, etc. 

Mithra 8-Gauge Bugpin Liners have a smaller diameter (.25mm) with a tighter grouping than our standard 12-Gauge Liners and are built with a tighter spacing between its needles. This grouping of 8-Gauge needles allows for finer lines to produce more detailed work and finer outlines than it's 12-Gauge counter part.
