The No. 4 model Is the most light weight model currently available from SOBAONE. This 5.7oz coil machine has an aluminum side plate/spring shelf with a steel coil shelf for decreased vibration and extra stability. The No. 4 also comes standard with my new spring loaded swing tube vise to easily hold any tubes on the market.
The No. 4 is limited to only 50 pieces and is available in black, purple, green, gold or magenta anodized sides.
