Cubles are the paper toy, re-invented. The officially licensed Pa Cuble is made of strong and sturdy paperboard, not your typical printer paper. They require no glue or scissors, great for a hands on, stress free activity at home or on the go. Cubles have moving parts held together by paperboard so they are playable without the plastic. And best of all their color coded instructions and patented engineering make each one fun and easy to build. Pa also comes with his own fun accessory! Cubles is headquartered in Minnesota. All Cubles are Made in the USA, 100% Recyclable and for every 1 tree used to make Cubles, the company plants 100 more by donating to OneTreePlanted. WARNING COKING HAZARD: Not Meant for Children Under 3. Once assembled, some of the parts become very sturdy. Although it is made of paperboard, please do be careful with the littlest ones.
