For local shipments, shipments usually take 1 to 2 working days after you have received the email with tracking details. If after 2 working days the tracking details is still not updated, do drop us an email at iwant@bowforbold.com with your order number and tracking number, and we'll assist you with it.
For overseas shipments through DHL and Singpost, the tracking link provided will usually work until the package leaves Singapore. This is because another courier will be taking over and the tracking changes. Don't worry! You can still track the shipment based on the airwaybill number through DHL and Singpost websites.

If tracking status is stagnant through the links as well, you'll have to contact your local Post Office for an updated status.
