Silver 38mm R3 Aluminium Lids for the 2oz Vintage Style Round Glass Jar or the 15ml or 30ml Cosmetic Jar.
If you are unsure on the size of lid you require, measure the neck of the jar from the outside to outside (do not include thread), add 2mm each side, for example if your jar has a neck of 59mm + 4mm (2mm each side) = 63mm
