Our STP has to go through extensive testing before it can be released into the market and that means backflow control, and leakage testing. 

​

After 3 new prototypes were sculpted, moulded and casted, that did not pass the QC, we've finally came to a model that did. 

​

With the budding inquiries, we've decided to release a pre-order for our Bundle Promotion. 

​

That means, the moment our 4th prototype is ready to go (scheduled 7th Dec 2020), your orders will be processed first. 

​

Your placement for pre-orders is an agreement that it will only be shipped 5-7 Days after the 7th of December 2020.
