Heritage & History
Tumi Ishi got its start in 2017 when its family owners, based in St. Charles, Missouri (a suburb of St. Louis), began making wooden blocks after loving the practice of stacking stones and thinking they could mimic the asymmetrical shape of rocks out of wood. What began as an experiment grew into a full product line of hand-shaped wooden "wood rocks."
Unlike standard square building blocks, Tumi Ishi's wood rocks are cut with many facets, making them more difficult and satisfying to stack, and the company designed them to promote creative thinking, mindfulness, and problem-solving through open-ended play.
Made in St. Charles, Missouri
Every Tumi Ishi block is made individually by hand in St. Charles, Missouri, with no set pattern used when shaping them - a process the company says cannot be replicated by machines, so no two blocks or sets are ever exactly the same. The company sources a diverse selection of sustainably sourced native hardwood species and finishes each piece with a proprietary non-toxic, natural finish rather than paint or stain, to showcase each wood's natural color and texture.
Blocks are sized larger than typical factory-made balance blocks, ranging from about 2 to 4 inches per side, a choice the company says keeps them safe for all ages while still allowing for countless stacking configurations.
