Home canners will appreciate this funnel's innovative design, which includes clearly marked measurements to help you estimate headspace when filling jars. The outer collar allows you to set the funnel on the counter without contaminating the inner portion that comes in contact with the jar. Fits standard and wide-mouth canning jars. Accurate, easy-read headspace measurements (1/4", 1/2" and 3/4") are printed on both sides of funnel. Outer collar keeps funnel off the counter when not in use to avoid contamination. Large loop handle. BPA-free polypropylene. Dishwasher safe. 3 1/4" x 5" x 7" high.
