These strong linen tapes do not stretch much. They have a tissue backing with an aggressive glue protected by silicon backing paper. (A five layer sandwich of linen~glue~thin tissue~glue~backing.) This method of manufacture leads to an economical product. There is some drop in strength over the Neschen tapes because of the tissue. We cannot speak for any wet-strength since it is not intended for use in damp situations.
We stock it in several colours. (Not all of which are yet listed.)
Aggressive glue means that, depending on what you are sticking it onto, you are unlikely to get a second chance. Removal usually results in a lot of damage to the material to which it is stuck.
