This is the strongest and the thinnest Invisible Elastic Thread on Earth!
The thread is wound on a spool by a custom made machine so there is no chance of the thread getting lost and tangled.
The spool contains a whopping life long supply of 1000 ft (more than 300 metres) ... Yes. A single strand of 1000 ft. The length of the thread is more than 2 football fields!
It has the greatest stretch-ability of all threads and is absolutely invisible in most light conditions, which makes it the most appropriate thread for making those magical invisible loops.
