Hi, We have mailed it out on 16 Dec 2017.
We check that you selected for Singpost Normal Mail delivery mode which is the slowest (minimum 5 working days after being mailed out). There is no means to track Normal Mail shipment. Singpost will deliver to your letter box. Please check your letterbox if you have not. Singpost does not work on Eve of Public Holiday, Public Holiday, Saturday and Sunday.
Please read our terms and conditions in our product listing page which we provided for you to make informed decision on delivery mode prior to ordering. We also attach it here for easy reference. Thanks.
