I just checked their 2017 catalog and it does not look like they make that string in reel form (at least in the US). I can follow up with our hard goods buyer to double check.
@graycrait did you end up buying a reel? I see that this is available now in US (still not in TTW), but when I checked the reel price, it came out more than $4 costlier per set than buying individual set - doesn't make sense. Some people may not do the math and buy this set thinking it'd be cheaper.
