Anna and Clara's living room cabinet is filled with all kinds of fun games and puzzles. From time to time, the sisters find themselves relaxing in their favourite armchair and solving a puzzle, such as this old classic.

"This quirky puzzle will keep you entertained for hours at a time," Anna says with a smile. "It is also a wonderful mental exercise."

The sisters' magic cube comes in a new design in various lovely patterns and colours and measures 5.6 x 5.6 x 5.6 cm.
