We are principally engaged in the design, development, testing and sale of a diverse portfolio of toy products ranging from simple plastic toy products to more complex electromechanical toy products. Our solution services span across the entire development stage of toy products from design, prototype testing, production management, quality control to after-sales services. We specialize in the development of infant and pre-school educational toys and learning kits. We started our operation in 2016 and have developed relationships with our customers mainly located in European and North American countries which possess renowned brands and intellectual properties in toy products. We have strong capability in product innovation, design and project management which allow us to provide product development solution to transform conceptual design into prototypes and further into commercialization of toy products. We have developed a nimble and low-fixed cost business model whereby our products are mostly manufactured and supplied by Fully Starise which represents approximately 85% of our cost of goods sold. Fully Starise is an independent third party supplier that operates a factory in the PRC. We consider Fully Starise a reliable partner and strong back up of production capability to us whereby we have entered into long term supply agreement with Fully Starise to secure stable and quality supply of toy products. Meanwhile, we are also currently exploring Vietnam and/or other Southeast Asian countries for potential locations for manufacturing operations. We plan to set up our own factory and manufacturing operations primarily to assemble components that we purchase from other companies. Although we plan to commence manufacturing operations, we cannot assure you that we will be able to materialize such plan and operations. Our principal executive office is located in Kwai Chung, New Territories, Hong Kong.
