These sturdy, clear glass jars are just right for your butters, creams, salves, bath salts, and more! The black, screw-on lids are made of polypropylene (tolerant of warm to hot melted butters), and are ribbed for easy gripping. The removable liners create a strong seal when the cap is secured tightly. Available in 1 and 2 oz (30 and 60 ml). Sold in packs of 4.
