This funnel is unique because it has an opening that is smaller than most canning jar funnels, yet it is wider than bottle funnels. This comes in handy when using jars that have narrow openings. It is a very high quality German-made product, and comes with a removable fine mesh strainer, which can be used to strain the tea when pouring it into the jars. The fine strainer is easily removable and this funnel also works well with a small kitchen sieve placed inside it. Great all around kitchen tool!
