I don't have experience with this, but I think Coach embellishments are usually securely attached. Years ago, I bought my daughter a sequin backpack and not a single sequin ever came off.Thank you for sharing this! Do you think they're attached with glue initially? I want to eventually get the Parker with quilting & rivets and am concerned about them popping off and getting lost since they're small. Does quilting come undone on that style bag? I'd rather have that one than the plain black, but I don't know how well quilting and rivets last. I have children.They don't intentionally damage my things, but the littlest will be interested in those little rivets.
