Most of our spices are sold in glass jars and re-sealable zip-top bags. The regular glass jars are 125ml or ½ cup in volume. This is slightly larger than a typical supermarket spice jar. The weight they hold varies widely based on the density of the spices or herbs you have purchased. For example, 125ml of salt weighs far more than 125ml of herbs.Our refill bags hold the same volume as the glass jars. We also offer one or two bulk sizes of most products.Certain items come in a smaller or larger jar, tin, or specialty container. This will always be indicated on the product page. Our small jars are 62.5 ml or ¼ cup, and our large jars are 250 ml or 1 cup. Large tins are 125 ml or ½ cup and small tins are 62.5 ml or ¼ cup.Empty jars, including extra large 500 ml (2 cup) glass jars as well as tins are available in the Accessories section of our website.
