Hello,

Yes, the address in Gangnam is our office.

We run a pre-order system where items are prepared only after payment.
This way, we can make sure that all items are top quality and in good condition.
It is always our top priority to satisfy our customers with our products. :)

For shipping, we use EMS as our courier.
