Two in one: With the help of the Twin Boxx, BRUNNEN has improved the learning method with index cards. The simple mechanism can easily turn one box into two – one for learning at home and the other one for learning when out and about. The appealing design coupled with the well thought-out Twin Boxx concept is outstanding. The Twin Boxx provides extra room for assorting the tabs in different ways, it is stackable and contains index cards in A8 size. The translucent pp material of the Twin Boxx is exceedingly robust, washable and available in three attractive colours: green, blue and orange. The bottom of the Twin Boxx is transparent.
