These black polypropylene spice caps include pressure sensitive liners with the words "Sealed for Freshness" printed on top. Once the closure is securely screwed on, the PS113 liner adheres to the top of the container providing further protection for your product. The 38 mm caps feature a single opening for pouring, while the other cap sizes have two openings; one side of the snap cap has 0.2" and 0.3" diameter holes for sifting, while the other has a larger spoon-size opening. These caps are ideal for packaging and dispensing a variety of herb and spice blends.
