The nephew and nieces often like to visit the sisters after school and do their homework at their house. Clara usually prepares home baked treats for them to enjoy while solving their mathematical problems, while Anna likes to make sure they have a few office supplies and accessories, such as this darling chalk board.

"The dear little ones can use the board to solve equations or practice their handwriting," Anna explains.

The sisters chalk board is made of MDF and pine wood. It measures 40 x 30 x 1.5 cm.
