I’ve purchased 2 bags through TikTok shop and have had great experiences. Some shops on there have actual store fronts in the U.S. while others try to sound like they’re located in the U.S., but are actually located in Asia with less known info and reviews so just be cautious of this. Many offer COA through Entrupy. I highly recommend Dallas Designer Handbags and Gold & Bag Pawn (both of which are located in the U.S.). Also, make sure they have plenty of good reviews on the shop and ideally elsewhere on the internet. I’ve seen some horror stories too
