The rookie girl group officially achieved their very first, certified all-kill on August 10 at around 1:30PM KST with their single "Whistle", topping every single major music chart as well as the Instiz 'Realtime iChart'!

"BOOMBAYA" definitely isn't far behind, maintaining a steady #3 spot on the same iChart.

Congratulations again, Black Pink!
