I bought my son a picture of three slate chalk + whiteboard and bought the accessories of the same brand ... What a disappointment ... very poor Products: chalk piece go on without even fallen ... felts are very fine mines so really not suitable for children ... and what about the brush to miniature painting .... I found at "Baker Ross" 1 pack of chalk dust of the brand Giotto for 4 £ 25 100 chalks ... they also chalks jumbo size for children. Anyway I'm not ready to buy a product brand JURA GAME
