1. Product Research and Development

We have an independent R&D team consisting of appearance and structural designers, electronic engineers and mold technicians. We also conduct extensive international cooperation with global designers. To enhance cross-border communication, we set up an office in Germany in 2017. By cooperating with renowned designers and collecting overseas market data continuously, we develop products that fit local market demands, ensuring our offerings satisfy mainstream consumer needs.

2. Product Production

We implement an open and efficient cost control model. We fully explore internal production potential to lower costs without compromising quality. Meanwhile, we maintain stable cooperation with reliable external partners to expand our production resources and optimize overall product cost performance.

3. Mold Making

Phone holder styles are updated rapidly. In-house mold development for every new style would cause high manufacturing costs and slow market response. Therefore, we leverage our foreign trade advantages to continuously source the latest popular models and promptly recommend trending styles to customers. We maintain a large phone holder database that is constantly updated to support diverse product selections.

4. Intellectual Property Rights

All suppliers are required to sign IP non-infringement commitments for every new model. We fully respect designers’ and developers’ creative efforts and provide reasonable intellectual property compensation. We aim to build a complete product-sharing industrial chain that enables original inventors to gain sustainable profits from every marketed product, inspiring more innovative and best-selling designs.

5. Services

We prioritize barrier-free and efficient customer communication. We currently provide localized services in multiple countries. Our staff communicate fluently with clients in their native languages to accurately understand requirements and achieve seamless cooperation. We will continue to recruit international talents to upgrade our localized services and bring better experiences to global customers.

6. Innovation and Development

We encourage customer participation in product innovation and welcome creative ideas to jointly turn original concepts into marketable products. For our IP-protected products, customers who pioneer local sales and meet specified sales volume standards are entitled to proportional commission compensation from subsequent local sales by other merchants.

On this basis, we have been maintaining business relationships with numerous customers for more than 15 years. We look forward to a long-term and trusting cooperation with you. Do not hesitate to contact us at any time if you have any questions, purchasing requests or special requirements. We will give you prompt and expert reply.
