This is a vintage spool of thread that is no longer made
so it is a good and rare find.
Mastex is a USA company that made this thread in the 1990.
I believe the stopped by 2004.
This spool is MSTX-743 color Bluebird and is bonded nylon and is a 2 oz spool.
This cord can be used for micro macrame for jewelery
or wall hangings. It was originally used for sewing leather and upholstery.
I have used it on Nicole's BeadBacking for creative uses and it works beautifully.
These spools sold for over $7.00 it is yours for only $5.00
Brand new never used in the packaging.
