Let the curved edge serve the transition
RM’s curved tip profile makes it a useful choice for transitions where you want a softer working edge. Build a background around the main shape, develop a tonal passage or blend one colour zone into the next. Keep a smaller grouping for a compact gradient and a wider one for a more open background.
Choose RM when the softer working edge serves the gradient. Compare M1 when broad directional filling is the main task.
Choose working width and needle body
1005RM and 1007RM are useful starting configurations for smaller sections. They use 0.30 mm wire with five or seven points. Choose five for the narrower working footprint and seven when you want more width without moving immediately to a large magnum.
The 10 series offers odd-numbered groupings from 5 to 27; the 12 series offers odd-numbered groupings from 5 to 23. The 10 prefix identifies 0.30 mm wire and the 12 prefix 0.35 mm. Compare the same count when changing wire—for example 1015RM and 1215RM—to keep a 15-point grouping while changing the individual needle body.
For a broad section that calls for a more substantial needle body, consider 1215RM; choose 1221RM or 1223RM when the area supports a wider grouping. Let the space inside the design set the width, rather than using the largest cartridge everywhere.
Professional quality for the broader working area
304 stainless steel needles and EO sterilisation form Thunder Pro’s professional needle specification. Selected to ATTO’s highest professional quality standard, the range pairs its working geometry with a standard universal cartridge connection for compatible pens.
Start with 1005RM or 1007RM for a smaller working section, then choose the width that serves your next fill or transition.
Which pack suits my use?
Choose 10 for introducing a configuration or keeping a secondary size available. Choose 20 for a magnum you use regularly, with more of the same Style ready for appointments and fewer repeat orders.
Which connection does it use?
The standard universal cartridge connection fits compatible tattoo and PMU pens using that format. Choose your needle grouping around the design and its working space.
