En la caja vienen 6 pipetas, como se indica en la descripción: 4 de ellas vienen en el sobre hermético de la propia caja y las otras 2 vienen sueltas (la caja realmente es de 4). Contenta con la calidad de Advantix, no me arriesgo a probar con otra marca. Muy recomendado por la relación calidad-precio.
