I have used OralB satin tape 25m in Australia and it breaks easily after a few uses.
I am not allergic to anything so if you know of a good strong longer lasting floss please let me know.
I have done some research and here is the best thread I have found (from 9 July 2018) so far.
Thank you very much.
Get those things that look like Loki’s weapon from Avengers (I’ve seen them at the chemist, but also places like Daisy/Miniso).
