Unfortunately, the term "strong" the true resistance of the tape is in my eyes not even close, I feel the green ribbon as a rather soft to medium.
I had different memories, a return but not worth it for this one item and I will look for this (for me too soft) tape in any way use.
I am glad to have a trial basis only bought a single copy and would also recommend to find out if what you have fits imagined under the strength determination.
Because for every "strong" or can "average" mean something else is as safe and more personal freedom in it and the manufacturer's specifications can serve only as a vague guidance
