Working with Velcro folders enables the child to concentrate largely on the content and not spending energy on writing/drawing. Another advantage is that the cards through the Velcro back do not slip, even in the case of motoric unrest, but are easy to handle. The Velcro folder are created according to TEACCH principles and show the child, material-immanently, when a task has been completed.

The folders are suitable for filling work-systems (e.g. 123 boxes).
