Most of the items are glass containers. Some listings note metal components for lids or bands, and one oil dispenser specifically lists borosilicate glass for the container.
Closures vary by style and include two-piece lids and bands for canning, one-piece metal lids for mini jars, metal caps or sprinkler tops for spice jars, and a drip‑free pour spout with adjustable flow on some oil dispensers.
Dispensing features observed include sprinkler tops for spices and precision pour dispensers with drip‑free spouts and adjustable (two‑speed) flow for oil or vinegar bottles.
Common design options include quilted/crystal patterns, flute‑shaped or diamond‑engraved jars, and plain transparent cylindrical spice jars.
Product descriptions and buyer reviews indicate that included lids and bands create airtight seals suitable for canning and food storage in many cases; reviewers often note that the jars “seal well for most uses.” However, seal performance can vary by style and brand, so confirm airtight/canning suitability in the product details and customer feedback before use.
