I was looking through several Scuolas on eBay since I can't find any stores near me that carry any and I noticed that some of the sellers that are usually really good about putting the backside of the zippers to show the "riri" marking don't show them. Do the scuola zippers not have the riri marking on them? There's one auction that I was looking at and there was a reflection on the zipper so I can't tell if it had the riri marking or not. I can't figure out what's authentic or not besides the riri marking since I'm not too familiar with Scuolas. Any scuola owners have any tips on what I should be looking out for in terms of fakes? Thanks in Advance!
