Description Reviews EcoJarz Grater - Stainless Steel Cheese Grater for Canning Jars Durable canning jar grater made of 304 stainless steel Use with cheese and grate on the go! Fits any wide-mouth canning jar EcoJarz Grater is a stainless steel medium-tooth grater lid that fits wide-mouth mason jars. Attach to a wide-mouth canning jar with a jar band and grate cheese directly into your jar. Perfect for jar enthusiasts, simple living, camping, and for use on-the-go. Made of 18-8 food grade 304 stainless steel and FDA-approved silicone. We recommend washing your new Ecojarz Graters thoroughly with soap and water before use. Dry them and your tin jar bands well after washing and store in a dry place. A “jar band” is the metal ring which threads onto a glass jar and is necessary to attach an Ecojarz Grater. It works just like a canning jar lid in that regard. If you already have a wide-mouth jar band, you are ready to go, but if not you can visit the Wide-Mouth Stainless Steel Jar Bands page and add one to your order.
