Like iuohkok said, send them an email saying which type/brand/model no you want. Then Ishibashi should reply within 1-2 business days and tell you if they have it. If so, they'll also tell you what the payment/collection procedure will be. By credit card or TT only if I remember correctly.

Once payment is made, they'll notify you of when they are shipping it and the EMS tracking number.

Once it reaches Malaysia, Pos Malaysia I think will send you a letter notifying you that it's ready to be picked up. Rest of the info is in the thread iuohkok mentioned, I think.
