Insul-Bright is a needle punched insulating material that reflects cold or heat back to the source! Perfect for lunch bags, potholders, grocery bags… Just make sure that you place the shiny side of Insul-Bright toward the hot/cold source.
Please be aware that Insul-Bright is heat resistant, not heat proof. You might want to add an extra layer of cotton wadding when making potholders!
Insul-Bright can NOT be used in the microwave.
100% polyester. Machine wash cool/machine dry low.
