Small case divided in half. You can put clean straws/utensils on one side and dirty on the other. Ideal for lunch at school, at the office, on the road or outdoors. Can hold about 4 straws and a set of utensils. They are made of the same waterproof, durable and durable fabric as our other popular products (washable diapers, training panties, waterproof bag, etc.). They can therefore be washed and machine dried but it is preferable not to handle them when they are hot.
