What payment methods can I use?
You may use electronic payment methods designated by the company, such as credit cards, overseas-issued cards, and simple payment services. Please check the available payment methods on the payment screen.
Does paying with an international card incur additional charges?
Yes, when paying with a card issued overseas, exchange rates and overseas transaction fees may apply, and these costs are borne by the user. You can check the exact amount through your card issuer’s billing statement.
A payment error (duplicate payment, non-approval, etc.) has occurred.
Duplicate payments or incorrect payments caused by system errors are eligible for a full refund immediately upon confirmation. Please contact Customer Service with your payment details (order number, payment date and time) along with your inquiry. However, errors caused by system malfunctions of the payment gateway (PG) company or user-caused reasons (such as incorrect card information entry) will be handled after the cause is identified.
Is payment information (such as card numbers) securely managed?
Payment information is not stored directly by the company, and is encrypted through a payment gateway (PG) that has been certified in accordance with relevant laws.
