Our Story

A Korean customer once told our sales representative, “When I received your quotation, I immediately deleted the quotations from other suppliers. Your documents are the most professional, and your responses are the fastest. Other suppliers were asking unnecessary questions, which was a huge waste of time. Your professional advice helped me triple my turnover.”

One warm afternoon, a sales representative received an email from a customer in the United States. The customer wanted to customize and design science toys and packaging boxes with their own brand information. After confirming the details with the customer, the sales representative worked closely with the designer to complete the plan and design drawings the next day. The customer, who had originally planned to customize 3,000 sets, increased their order volume to 7,500 sets.

These are just two examples of the many satisfied customers we have served. We are committed to providing our customers with the best possible service, and we are always happy to help them achieve their goals.

Core Team

Our team is comprised of individuals who are passionate about science, education, and children. We have a strong understanding of the STEM education market and the needs of our customers. We are also a group of big children ourselves, with a strong hands-on ability, creativity, and imagination.

We are able to turn household waste into funny and cute robots, and we can also turn flour and clay into amazing artwork. We are confident that we can help you make STEM kits that are both engaging and educational.

If you are looking for a partner to help you bulk STEM kits, we would be honored to work with you.

We welcome you to join us in the joy of STEM education.
