I bought this item in Vietnam, attracted by its gold color and crown. I attached it to the center of my carry-on bag using strong adhesive tape ⭐︎ It's completely sealed. While I can't guarantee it's completely safe for carry-ons, I've also attached it to my backpack at times. This is the last one I have in stock. Considering the shipping costs, this is the lowest price I can offer. If it doesn't sell, I'll keep it for myself.
