2 x 21g sticks Golden Vale Light Original Cheesestrings are a HEXA as are 2 Dairylea Rippers (which I think are a similar thing). I have a feeling the Golden Vale one is different to the Cheestrings you can get just about anywhere but I may be wrong
Edit: From what I can figure the Golden Vale ones are the ones you see all over the shop. So long as you've got the light ones you should be fine.
I couldn't find these on the online help either - tried every-which-way to spell - then found they were by Kerry Foods and put that in but only cheese comes up not the cheesestrings - sorry I couldn't help, was on this forages.
