This is an item for sale, imported in bulk for personal use. These are budget strings, but my personal impression is that they are better than the strings sold at a certain musical instrument store. I set them up normally on a Floyd Rose. The next day, the tuning was only slightly off. They were usable without any problems as practice strings. Strings are getting more and more expensive these days, so it's becoming difficult to find good strings at a low price. I think these are a good product in terms of price and quality. Important notes: The strings are generally shorter. The 1st string is long, and the 6th string is short, so I couldn't wind the 6th string on my reverse headstock guitar (where the 6th string is furthest from the headstock). There were no problems with normal headstocks like Les Pauls and Strats. Please note that these cannot be used on reverse headstock guitars.
