Claims to be double wall…NOT. Ill-fitting screw lids, too.
I have a few double-wall 4 ounce jars of this exact type and external style, from a vendor I use regularly.<br />This lot of 12 appears to be half that size, when examined externally, but when I measure the contents, it's an  honest four ounces.<br /><br />I find the inner liner lids a nuisance after first opening. Tossed it.<br /><br />And screwing the cap back on whether it's after I fill the jars or when I am using them, it is ALWAYS difficult to get them to thread correctly! Waste of money.
