It's time to play, What Is This Kitchen Tool!
I'll give you one clue, this one is flexible.
To find out what it is,
This wacky device is actually called The Foodloop. It was designed as reusable kitchen string. Made from food safe silicone, the Foodloop is heat resistant to 675F and can be used in the freezer too (just don't put it over an open flame).
Looks like it could be pretty interesting, sort of like a food safe zip-tie. Say bye-bye fancy french knots! The website shows it wrapped around roulades, fish, leeks and more. Available for $14.95.
