https://en.wikipedia.org/wiki/List_of_best-selling_albums_in_South_Korea S.E.S has the best selling girl group album ("Love") in kpop history with 760,475 sales in 1999. Their other album sales are big numbers too: 1998: 651,330 1997: 650,000 2000: 626,565 Only Fin.K.L with 593,816 album sales ("White") in 1999 stands between Twice and S.E.S. Twice saled with Twicetagram 525,405 albums in 2017. For me Twice is the only girl group right now which could break Fin.K.L. record. But could they break the all time record of S.E.S? 760,475 is a really big number. Twice is without doubt the best selling girl group for the third generation but could they break these numbers with only one album? The benefit for S.E.S and Fin.K.L. was that to this time only physical albums were an option. And please don't name other artist than Fin.K.L. and S.E.S. Don't want this thread to end up in a fight.
