Review on PEMOTech Prime Kitchen Funnels Set of 3 - Large 304 Stainless Steel Funnel with GRAVITY3D Technology for Faster, Drip-Free Transfers - Includes 2 Strainers, 2 Silicone Tubes, and 1 Clean Brush by Patricia Goliday

These funnels are very sturdy and fit small bottle openings without restricting flow. Plastic funnels offer many other limitations. The description doesn't say how big the stems are, which is important. So here are my measurements. The large has an outside diameter of 0.50 inch, the medium 0.36 inch and the small 0.25 inch. The material thickness of the stems is 0.018 inches, the body is 0.023 inches. The funnels fit inside each other and can be stored like this. The clip ring and cleaning brush feel comfortable. There is one drawback - the transition of the stem into the body is not smooth. It is either corrugated or welded and there is a significant step where liquid or powder collects and is difficult to clean. Keep this in mind.
