Wrap (or rewrap) your tenon joints. Great when humidity and temperature changes make the joints too loose or sticky tight.
This red, twisted tenon thread is the exact thread used by Fox on their bassoons. It can be used over cork, if the joint is loose. Useful for baroque oboes, and other instruments with wrapped tenons.
50 yards. Enough for about 10 instruments, or 30 tenon wrappings.
