MBT Waxed Thread - Black, 200 Meter Spool Setter base (sold separately) isThis thread is made in Japan from 100% polyester yarn. What makes it special is the technology behind it: a heat bondable yarn is inserted into the center of three twisted yarns. When heat is applied, the inner yarn melts and bonds the three together from the inside, creating a strong, stable core. This unique structure gives MBT its signature shape memory, it resists unwinding and naturally returns to its original form, even if twisted or loosened.
