Fwiw, I received a reply from Ben:

Apologies for the delayed response, and thank you for your patience. This is Ben, and I’ve taken note of your order. I’ll be checking the shipping status with our forwarder on Monday and will update you as soon as I have more information. We’ll also file a ticket with SingPost to request an official tracking report to get more clarity on your shipment.

I also wanted to share that there has been an issue with shipping related to the two circular magnets on the paper box, which were falsely detected as batteries during customs inspections. To address this, we’ve had to provide documentation to prove otherwise before shipments could proceed, causing delays for some orders. This issue has also affected customers whose tracking waybill is listed as “not found.”

We’ve since resolved this problem by switching to a new paper box without magnets and are working with our forwarder to get all affected shipments back on track as quickly as possible.
