🥤 2. Step-by-Step DIY Assembly: How to Make It

Step 1: Buy & Open Your Large Ice Cup

Take your 3 items to the cashier counter and pay using your T-money, WOWPASS, or foreign credit card. Peel off the clear plastic seal on top of the ice cup.

Step 2: Pour the Banana Milk First (The Base)

Peel the green foil of the banana milk and pour about half to two-thirds(60%) of the bottle directly over the ice.

Step 3: Pour the Coffee Pouch (The Sunset Layer)

Tear open your coffee pouch and gently pour the dark coffee over the top. If you pour slowly, you will get a gorgeous two-tone gradient effect that looks amazing on camera!

Step 4: Stir & Sip!

Pop on the cup lid, grab a plastic straw from the counter, stir the layers together, and enjoy the creamy sweetness of banana blended with rich roasted coffee.
