A perfect solution for organizing any area in your home or shop. Our 32 ounce 1 liter by liquid clear plastic jars are clear as glass but are lighter in weight than glass jars and are impact resistant. Our caps feature a foam liner, which helps protect against odors and will not impact the taste of any food items you store. They are made out of Polypropylene (PP) and feature ribbing on the sides for easy opening. PET plastic does not have a high temperature resistance, less than 120 degrees so they are not dishwasher safe or microwave safe. But they can be placed in the freezer up to -30 degrees. The recycle code for PET plastic is 1. The diameter of the jars are 3.69 inches with a height of 5.98 inches without the cap on. We shrink wrap these to protect them. Plus both the jars and caps are made in the USA. In fact, 95% of the products Pinnacle Mercantile sells are made in the USA
