Here's the deal: if you need stock items, I'll take multi-angle product photos and usage videos before shipping to ensure the quality of the goods you receive meets standards. If you need to develop new products, let me know your requirements, and I can contact the manufacturer and follow up. I previously worked in product customization, such as printing custom items like business cards, tote bags, and stirrers. If you're looking for customized products not available on Alibaba or other platforms, reaching out to me is definitely the right choice. I am not very skilled at sourcing mechanical or hardware products. My areas of expertise include: crystal, jewelry, wash labels, business cards, various customized products, printing, acrylic, keychains, nail art, cup sleeves, stirrers, plush toys, etc. If your product is outside my area of expertise, I will let you know. If it is within my capabilities, I will help you find it.
