Spare part: pink tower cube 1 x 1 x 1 – Nienhuis Montessori

All Nienhuis Montessori materials are produced in factories certified by the ISO 9001-Quality Management System Standard and the ISO 14001-Environmental Management System Standard.

The main production principles of Nienhuis Montessori are quality, safety and durability:

• Raw materials are tested according to EN71-3 safety and quality standards and ASTM (American Society of Testing Materials) of the countries they are destined.
• All lacquer and paint is controlled immediately after it has been received. Every delivery is tested by a certified testing device.
• A repeatable procedure is applied during the design of each single product, avoiding overlooking safety issues with regard to the product material, design, and technology needed.
• A physical safety test is done for the first batch of each new product. If any material is improved products are re-certified to meet all safety and quality standards.

Nienhuis Montessori materials are made according to the blueprints as first specified by Maria and Mario Montessori, and present day by the Association Montessori Internationale (AMI) Materials Committee.
