Callero

Callero isn't just a single storage unit, it's a whole range of modular units that lets the educator choose the storage solution to suit their specific needs. You can build up or across and combine tray units with shelf units to provide a classroom learning area that contains everything pupils require for their lesson.

Callero is designed to be friendly and fresh looking, well detailed and robust, and ideally suited to its environment. It is also logical and straight forward to assemble by non-specialists, and simple to adapt and expand.
