Can you help me make my own design? How about the sample fee and sample time?

Sure. We have a professional development team to design new items. And we've made OEM and ODM items for many customers. You can tell me your idea or provide us the drawing. We will develop for you. As to the sample time is about 7-15 days. The sample fee is charged according to the material and size of the product. but we will refund the money when you place an order.
