I just did a quick search for a tiny on eBay and was disgusted by the amount of “new” fakes coming out of Japan now! They’re making a liar out of me! There are still some nice ones though. And they have a hot pink tiny! I’m attaching the link. And I’m not sure if you’d like a couple others I found.I'm so glad your friend loves the tiny! You definitely gave me an idea to look around Ebay - especially Japan - for a tiny Falabella. I can't wait to see it! Wow 3 days from Japan!
I admit I had to look up your Belstaff bag - never heard of it either. There are some incredible deals out there if you know how to authenticate your own bags and I've gotten a few great deals but for the most part I find people tend to overprice their bags. I can't believe you found a mini for $200. My first Falabella 3 chain was second hand in pristine condition. At the time, I didn't know if I would love the bag and wasn't willing to pay full price for it. I think I got it for about half the price of retail.
The Fendi Zucca baguette is exactly the one I want...the classic. I have been to the Fendi boutique to try it on. Love it! I'm not a person against logos. I might try to see what is in the second hand market.
I tried selling through a couple of the big second-hand sites but I find the amount they offer is much lower than what I can get directly. It is obviously harder to sell directly but you can mostly tell who is serious and who isn't.
And what a great sister you are! Your sister is pretty lucky to get such lovely LV gifts.
As for the baguette you can definitely find a tobacco Zucca for less than the boutique. Even on Poshmark and Mercari you can find hidden gems. But some people try to sell bags that should be tossed. What size Zucca do you want? Mine are the mama size but they make a smaller version. I have the zucca and 2 zucchinos. I’ll keep an eye out for you.
Most Belstaff bags aren’t known for being aesthetically pleasing but highly durable. It was odd that Saks was selling this one. But I’ll find a picture of it and show you.
Here’s a couple tinys I think are nice based on what you sent me pics of.
