This fire engine has it all! It comes from Klein and is ready for any fun and use. The tank holds two liters of water and can be carried like a backpack, turning every game and every water fight into a wet experience. Theo Klein's fire engine products are very popular with children because they help them imagine themselves as brave and helpful firefighters. Role-playing games like this are extremely important for children's development: By imitating the movements and actions of adults, children train their motor skills and, through interaction with other children, learn a great deal about social rules and expectations. Through play, they foster their imagination and creativity—and have tons of fun in the process.
