The extended Dienes set helps children understand the principle of the decimal system in a playful and illustrative way. Using cubes, sticks and plates, children can easily learn to work with units, tens, hundreds and thousands and better understand the structure of numbers. The set is suitable for counting, decomposing numbers, comparing values and creating mathematical problems. By manipulating the individual parts, children naturally develop logical thinking, mathematical skills and spatial imagination. The tool is ideal for teaching mathematics at school and practicing at home.

RE-WOOD is an eco-friendly alternative to plastic. It consists of 100% recycled and natural material with PEFC certification. RE-WOOD products are safe, strong, lightweight, and saliva-resistant. Wissner has been working with this material for 10 years. It is produced in an environmentally friendly way from crushed wood residues (a waste product from German wood processing plants) and recycled binders. The material can be composted if given enough time to decompose.

All plastic parts of Wissner educational aids are made from RE-PLASTIC. Its production uses 100% recyclable polystyrene from post-industrial waste. It is recycled on site and then returned to production. RE-PLASTIC can be recycled over and over again and is fully equivalent to PVC in terms of quality, appearance, and feel. Environmental protection without compromising product quality.

The PEFC (Programme for the Endorsement of Forest Certification) certificate guarantees that the wood from which the product was made comes from forests managed in a careful and sustainable manner and that the highest environmental, social, and ethical standards are observed during harvesting. PEFC criteria are regularly reviewed through a process of global consultation with research organizations, governments, the public, businesses, and employers, taking into account new scientific knowledge and social changes. The PEFC label on a product means that by purchasing it, you are helping to protect forests and supporting sustainable and responsible management, which will enable forests to be preserved for future generations.

In 1976, Jürgen Wissner founded a company in Bensheim, Germany, to manufacture mathematical aids for schools. The motto of this family-owned company, which focuses on future generations rather than quarterly financial statements, is "smart products for bright minds." In 1982, they added educational aids for children to their portfolio. The company continued to develop, manufacturing products based on the principle of active learning through play. Wissner gradually switched from ordinary plastic to recycled plastic, and later, in 2012, took another step towards greener production by replacing plastic materials with 100% recycled wood waste. More than 90% of its products are made from these recycled materials. Wissner has also expanded its product range to include linguistic educational toys, teaching aids for traffic education and meteorology, and educational games focusing on mathematics. Since 2015, it has been manufacturing most of its products from recycled wood. In 2018, further major changes took place, from a redesign of the company, setting new goals and values regarding production and materials used, to the production of completely new types of educational toys. The recycled wood from which Wissner manufactures its products obtained PEFC certification in 2023. This means that it comes from forests that are managed in a careful and sustainable manner. The recycled material is free of harmful substances, and the wood used, especially sawdust, comes from Germany. The company tries to source as many of the materials it uses as possible from EU countries. The products are manufactured in Bensheim, Germany, and southern Hesse. Wissner not only produces useful teaching aids, but also educational games that make learning fun, engage all of children's senses, and support their individual talents. Wissner products enable multidimensional learning according to Pestalozzi and can be combined with each other. Thanks to state-of-the-art production facilities with heat recovery and the use of solar energy, they achieve almost CO₂ neutral production.
