**Production and supply chain process**

1. Design and R&D: Design the strap size, buckle structure, air holes, magnets, etc. according to the customer's watch model (such as Apple Watch, Huawei GT series).

2. Mold development: According to the customer's order quantity, reasonably develop molds suitable for the customer's cost

3. Material selection: Choose to use different grades of raw materials according to customer needs, such as food-grade liquid silicone (environmentally friendly, non-toxic, anti-allergic), medical-grade silicone (high elasticity, high temperature resistance).

4. Functional testing: tensile strength, sweat corrosion resistance, UV aging resistance, magnetic GS value and other experiments.

5. The order delivery date depends on the customer's order quantity.
