Meet the Mainstays 4 oz Mason Jars, a set of 12 mini canning jars sized for small portions and small-batch projects. Each quarter-pint jar holds 4 ounces—about half a cup—making it a handy fit for jams, dips, spices, honey, and sauces, as well as craft storage and homemade gifts. The regular-mouth opening gives you room to fill and pour, and the decorative quilted glass design adds a charming, display-ready look for party and wedding favors, holiday presents, or visible pantry and craft organization. Supplied with matching lids and screw bands, this 12-jar set works for everyday storage, small preserving projects, and creative uses around the kitchen and craft room.
