- Origin -
KOSO was officially established due to the realization that an independently developed brand is indispensable for future market marketing. Therefore, KOSO was registered as a T&S trademark in 1989. The name KOSO is derived from the Japanese words for "conception" and "high speed." Conception represents creativity, while high speed represents high-performance expression—combined, they reflect the company's hope to use creativity to create high-performance products!
- Spirit -
The brand spirit pursued by KOSO is to build quality, technology, and service on the foundation of integrity and mutual trust. We persistently hold this attitude, not only manufacturing high-quality products but also pursuing product innovation and quality improvement, hoping to bring more excellent products to everyone.
- Brand Journey -
Pursuing perfect product design and quality has always been our goal. Therefore, KOSO constantly spurs itself on by improving its own technology. We firmly believe that brand image and product quality are synonymous! Therefore, the company has strict requirements for product development, production processes, and quality control, hoping to achieve the goal of high quality while stepping onto the world stage. In the future, KOSO will continue to develop more user-friendly and innovative products, and hopes to become the next world number one from Taiwan within ten years, another pride of Taiwan, and the pride of the Taiwanese people.

[Notes before ordering]
Before ordering, please confirm the color, size, and other information you wish to purchase.
Most products have delivery times provided after the order is placed, so there may be situations where products are discontinued or require a long wait for shipment.
If an order cannot be established due to factors such as manufacturer stock shortages and temporary inability to deliver, it will not be established; if the order is not established, no fees will be charged.
Please understand that the manufacturer may unilaterally change specifications or exterior designs, resulting in packaging or body styling that differs from the images on the product page.
If the product cannot perform the functions expected at the time of ordering due to the manufacturer's unilateral changes to product design or specifications, please consult our customer service for subsequent processing.
Products go through multiple shipping processes from ordering to shipment, so packaging may be deformed or damaged during transportation, but the product itself is intact and can be used normally.
[Return Notes]
If you need return service, please apply in the return section; and please keep the product appearance and seal it well with the original packaging box.
When we receive your return application, we will send a logistics operator to pick up the goods as soon as possible.
For returns of non-human damage defects, please apply for a return within 7 days of receiving the product.
[Authenticity Guarantee]
For products with an authenticity guarantee, if they are found to be suspected counterfeits and have gone through relevant litigation and are finally judged by the court to be true, customers who purchased these products will be compensated 10 times the original purchase price.
