Benecchi GBP tying thread
The spools designed by Giorgio Benecchi GBP Tying Thread have a side capsule for thread locking, in different colors according to the family of yarns.
The edges of the spool are micro-knurled to allow a controlled release of the thread with the spooler. Inside the bobbin, the shape of the points of contact with the spooler pliers is designed to obtain the best friction.
