I stumbled upon your Yotube page by accident and almost fell off my chair, how natural this system looks, especially the hairline. I particularly like the way the hair runs into the sides. A weak point of many of the 90% hair systems that is easily recognizable to the eye.The hair moves, has gravity when you shake your head, at medium length. Quality like from the film industry. Congratulations to Lord Hair.
Your best bet would be to bulk buy systems. and bring along 2-4 systems. And potentially give an emergency system with additional supplies to a family member or friend, so they could ship it to you if your bag got stolen. If you are not in one location for long it can be difficult to find a place to ship overseas, especially when it could take like 2 weeks to arrive.
We ship worldwide and have customers all over the world so Thailand or other countries would not be a problem. As long as FedEx or the other international couriers can reach you then we can get your hair system to you. Delivery time will still be around one week. As Jake says, it would be good to travel with some spare hair systems and giving one to someone back home sounds like a great idea.
