Our adhesive metal strips are designed to go on the outside of your cloth face mask. We recommend hand washing your mask with the metal strip, or removing the strip to machine wash.
We cannot say how many times you can hand wash your mask or remove and replace the strip, but we have successfully done both options multiple times in our testing. Hand washing with the strip in place seems like it will last longer.
You can place these on your mask wherever it is the most comfortable for you!
10 strips per pack - mask not included.
