From Tiemco Products of Japan comes their Double Arm Adjustable Bobbin Holder.
The design replaces the "master bobbin holder" from Tiemco that was discontinued a couple of years ago.
The innovative design of this bobbin holder holds the thread spool with four stainless wires.
The four wires feel very comfortable in the hand and gives an improved sense of grip.
The ceramic tube can be adjusted vertically to any position to suit your vice height and tying style.
