Purchase service in the second markets like Bunjang is available?

Yes, it’s possible. Bunjang purchases are charged the standard assisted purchase fee (5% of the total amount, minimum 5,000 KRW) plus a special fee of 10,000 KRW. For example, a purchase under 100,000 KRW costs 5,000 + 10,000 = 15,000 KRW in fees.
