I have to admit I thought this was a joke when i first came across it, but it appears not, they have been prominent on the UKRSA website. One difference with this brand is that only certified stringers can purchase the string. One reason I guess for ensuring your stringer is certified, as this is one example of the material available to certified stringers. I will be purchasing a starter pack soon to try and will report my findings on a new blog.
