Hi Everyone，
I am honored to announce it to everyone.
ST-2 has entered the end of research and development.
We are currently choosing between ultra-fine fiber and sub-fine fiber specifications.
But we still want to leave the final decision to everyone.
We try our best to send both fiber brush knots to everyone for testing.
The final ST-2 specifications will be decided based on everyone's feedback.
We hope to provide a fiber with the ultimate touch, using the same DONGLI material as ST-1.
The difference is that we use a more sophisticated production process.
In fact, we have also considered South Korea's Hyundai fiber, but this fiber processing technology is not mature yet, and this material may be used in the ST-3 launched in 2025.
In fact, when we were developing ST-2, we wanted to try a spiral wire structure, which has stronger water storage performance, but it was difficult to make and the cost increased. So I can only give up.
Everything takes time to complete.
Fortunately, we still have a lot of technologies that we can try and can provide you with more surprising products in the future!
Best regards，
Carry
