Material: Nylon

One yard ribbon will press about 10-12 of our largest square tins, and lots lots more of the smaller tins. The ribbon is somewhat reusable because you don't have to press just once and then toss the ribbon away. As long as you are working the same color, you can use the same piece over and over again.
