MAKE SURE SHE SENDS IT EXPRESS INTERNATIONAL! It includes insurance 3-5 day delivery and tracking + signature.
If you go 1st class international you run the risk of never seeing it again. There is no way to check where your package without Express service, it is the most expensive but it's worth it for high valued items. Express is pretty expensive but if anything happens to it you are covered by insurance, just make sure they upgrade to the retail value because it only comes with $100 by default.
Trust me I ship a lot of street wear internationally and once the product hits over $200 I make all buyers pay for international express mail - it protects both of us.
