Though packaged in foil too, the PNG I tried strangely came with none of the lubricant provided with either Babolat's VS or Wilson's NG, and was limp and dried-out by comparison then. Even so, I was shocked when one of the mains snapped on my electronically-controlled, computer-chip supervised machine as I was stringing it up, which hasn't happened to me with gut in, oh, say, the last 15 years, at least.
Though Made in France, it said, this PNG reminded me of the old English-made Bow Brand gut version, which came out of the package the same way, and which, though it played well enough then (it didn't snap while stringing it, most of the time), didn't last terribly long, particularly when compared to VS.
PNG can be had for less that the usual $40/set I paid, if you look around; not the best sign for what purports to be a prime natural gut, to begin with...
