This is a small bookbag by Cath Kidston crossover with Matlida, a limited edition with lovely Firework Floral pattern in Cream color. It should be a very good collection if you like the story by Roald Dahl. It's a water resistant bag which could fit in a bottle of 500 ml water and your lunchbox.
Size: 21.5 x 20 x 9 cm.
