Bueno
Muy buen producto. Les aconsejo agitarlo y al final sacudirlo hacia la base, con la punta hacia arriba ya que de lo contrario la diferencia de presión de la burbuja de aire dentro del resilience puede hacer que brote el contenido. En mi caso el producto fue algo espeso y tardó en asentarse. Cumple su función a la perfección. NOTA Cuenta con una indicación de ser posible generador de cancer .
