Borndea’s educational toy that can be enjoyed by everyone from age 0 to 100 has been produced entirely in Japan using domestic materials. Invented by an engineer and developed by an infant-toddler educator, unlike regular block toys, Tsunotsuno series offers various ways to play through different actions such as stacking, rotating, connecting, and rolling. They can be also used at swimming pools and baths as they float in water. In addition, you can wash the blocks in a washing machine by using a mesh laundry bag so that they can be kept clean. Having acquired the Safety Toy Standards and EU Declaration of Conformity (DoC) while complying with the CPSIA (Consumer Product Safety Improvement Act), Tsunotsuno series can be enjoyed by anyone with peace of mind and appreciated by a number of facilities nationwide including kindergartens, nurseries, schools for children with special needs, and elderly facilities. In addition, it has been certified by the Wonder 500, Tokyo Innovative Recognition and Trial Purchase Program and the Good Toy Award. Having acquired design registration in Japan, the US, EU, China, Korea, Taiwan, and Singapore, the company has been working toward export sales since last year.
