How does this website work? 

Our items are either Ready Stock or Preorder items. Our weekly promotion starts every Thursday 12pm(Vip preview at 10am) and ends at Sunday 11:59 pm! So, check out our menu under ‘New - This Week’s Spotlight' tab every Thursday!

• Ready Stock: If it is a ready stock item, there is no special mention in title and product intro. It will be delivered within 2-5 business days after order confirmation.
• Preorder Items: Product title starts with [PREORDER] and the intro starts with closing date of preorder and estimated arrival date. Delivery will take normally 4-6 weeks (Korean brand will produce and send to Singapore. In Singapore, we need to do trimming and quality check for every piece, so it normally takes 4-6 weeks.) For preorder items, you can check estimated arrival status in the menu PREORDER STATUS: Link
