Hi mylala,
I found some great suppliers of microfiber cleaning cloth for you. They ship worldwide except for microfibertech.com and simplygoodstuff.com (based on what I saw on their site). What I suggest is for you to contact them to confirm this and of course, negotiate with prices, ask if you can get samples, etc. Before you do though, remember to check this link (if you haven't yet): Link hidden: Login to view and only pay using PayPay or credit card.
Here are the links to their websites:

Although the above suppliers are not in our directory, they should be safe to deal with. We have checked out their sites and found that they are well-established companies. They also accept safe payment methods such as Paypal and major credit cards, meaning you can get your money back fairly easily if something goes wrong.
However, please note that we cannot guarantee the safety of any suppliers outside SaleHoo.
Hope that helps! Cheers! :)
