- The city mountain for area follows in the part item and the delivery carriage separate way it could be levied.
- General Lgistics/mail delivery (order one, holiday exclusion): Change of air reverse 3~7 one
- To the case which does the on-line remittance from the payment confirmation day it includes in delivery duration.
- Case 100% exchange and the exchange which are flaw to the goods non it is possible, the delivery carriage the total amount charges from normal sports
- The case which is not above to the goods (the case which is not above to packing and the contents water) exchange it is skillful wrongly and the delivery carriage is customer charge
- Goods flaw occurrence hour returned goods it is possible within 20th.
- Daum (one mail) the mail is caused by with on-line stamp my execution and the order confirmation mail is not sent out. To record the mail of the next mail outside, it wishes.
