Compatible with 3RL to 18RL, this aluminum jig allows you to easily adjust the needle tips of the round liners of pre-made needles. When you feel the tightness of the circularly assembled needles is too tight, you can use this jig to slightly widen the distance between the needle tips to fine-tune a slightly thicker and thicker line. To use, simply select a hole size that will not disrupt the circular shape of the needle, insert it, and sear it with a lighter flame. This is convenient because it will not widen beyond the selected hole size.
*It is recommended that the jig before use and the needle after adjustment be sterilized with Ganesha Hachiroku.
