These red polypropylene spice caps each feature pressure sensitive liners with the words "Sealed for Freshness" printed on top to further protect your product. These PS113 liners adhere to the top of the container once the closure is securely screwed on. The 38 mm caps have a single opening for pouring, while the rest have two; one side of the snap cap has three holes (0.2" and 0.3" in diameter) for sifting, while the other has one spoon size opening, making these caps ideal for packaging and dispensing a variety of herbs and spices.
