Groz-Beckert 134 MR R (regular round point) size #18. 1 package consists of 10 needles.
The Groz-Beckert MR needle style is specifically made for multi-directional use, which is exactly what longarm machines need.
Multi-directional design means more accurate stitching while moving the machine in any direction. The MR needle style has maximum flexibility and bending to help reduce needle breaks and a deep scarf to mitigate skipped stitches.
