This experience yields stable dimensions and minimal variation between production batches, which is particularly beneficial for products that require continuous restocking.

Customers can communicate directly with the production side regarding order planning or adjustments, reducing delays or misunderstandings caused by intermediaries. For buyers who value supply stability and predictable execution, a self-owned factory model offers greater reliability in practice.
