OSK was founded in Osaka, Japan, by a team of home cooks and engineers who were tired of messy, inconsistent onigiri. They saw how modern life made it hard to pack a satisfying, traditional lunch. Their mission was simple: make perfect rice balls accessible to anyone, anywhere. They spent 18 months developing the LS-20, testing over 50 prototypes with families and office workers to get the shape and seal just right. Every component is manufactured in a Japanese facility certified for food-grade production. The result is a tool that has become a staple in over 200,000 Japanese households, consistently ranking as the top-selling onigiri maker in its category for its foolproof design and portability.

The OSK LS-20 Compact Dual Onigiri Shaper and Portable Rice Ball Case is a kitchen tool designed for shaping and storing onigiri (Japanese rice balls), and as such, it does not contain consumable ingredients but is constructed from specific materials. The primary material is food-grade polypropylene plastic, chosen for its durability, lightweight properties, and safety for direct contact with food. This plastic is non-toxic, BPA-free, and resistant to stains and odors, ensuring that the shaper and case maintain hygiene and do not impart any unwanted flavors to the rice. The design includes a dual-functionality feature: one side acts as a mold to shape rice into uniform triangles or rounds, while the other serves as a portable case with a secure, snap-lock lid to keep onigiri fresh and intact during transport. The inclusion of these materials and features offers significant benefits to users, such as ease of use for consistent rice ball formation, portability for meals on-the-go, and easy cleaning due to the plastic's smooth surface. Overall, this product enhances convenience and efficiency in preparing traditional Japanese snacks while prioritizing food safety and user-friendly design.
