3 Vintage/Antique Salt & Pepper Shaker Sets- From Italy, Japan, & 3rd Unknown

Nippon Noritake blue floral set have hand painted on the bottom "A S.C. 1910" and I can't find any matches for them - so I don't know what they're actually worth - I added a screenshot of the closest ones I could find for price comparison and description purposes.. The second pair have no makers mark either - but hand painted on the bottom is "Made in Italy".. But of course I forgot to take a picture before I wrapped them back up. (It's on my list of "to-dos"..) 😬 The third pair are also unmarked/unlabeled- and one has a lot of crazing- as seen in photos... Please see all pictures and feel free to ask questions. Screenshots were added for price comparison and description purposes only. (Best matches I could find.) 🫤 I'm always happy to offer bundle discounts/combined shipping so be sure to check out my other listings! 🙂🙃🙂
