If you are looking at this listing, you know exactly what these labels are and what they are for

They are made from waterproof / fade resistant / rip resistant material.

They will not fade or damage like paper ones do, no matter how much they are handled

You will need a  permanent marker, like a sharpie etc, to write on these. They cannot be written on by a normal pen or pencil.

This ensures that nothing, including the handwriting will fade through the period that the label is valid for.

The labels are 40mm long and 20mm high. If you require other sizes, please contact me.
