You might have found yourself asking "what the heck do those PP and SS sizes mean?" or you might have been a bit more genteel. All the same, you might have wanted to know. Heck, everyone uses it and Swarovski most certainly does.
So what do they mean and can you find some table to refer to? Who wants to spend good money for a project only to find you got the wrong size.
This info-sheet Sizes PP, SS is what Swarovski means. Bookmark it. And as always, you are welcome to throw feedback/questions my way.
