Question: outer diameter of smallest funnel (inches)
Document: Durable for its weight. I use the smallest of these with a flexible straw to get liquids into tight places.
I got these funnels for mixing my dyes for tye dying. they work great but the smallest one is REALLY small.
They are cheap funnels that make pouring into small openings easy. The smallest one is good for flask filling, and I will use the largest for home brewing (though it could be bigger).5 stars for price and functionality.
These are actually bigger than I thought they would be even after reading the size description. I wanted the smallest one for filling tiny square and piggie containers for a Bento box. The littlest one does work well despite my thinking it would be too big. I was easily able to fill a square container with salt and not spill one drop. I am sure I will find plenty of uses for the other two sizes. A good buy for the money.
They funnel stuff. And that's about all I have to say about that.
The largest funnel is not as large as I needed it to be but it does funnel properly so its okay.
Not sure how one can mess up a funnel but these people did not. There was nothing wrong with them and the plastic was smooth.
got what i paid for 3 Piece Plastic Funnel Set that what i got no more no less thank you
The material on these was surpisingly cheap/poor but they do funnel, which is the goal. They will do the job until we can invest in something better.
What can you say about a funnel? It's big at one end and small at the other. A quality product, happy with my purchase.
Answer: The mouth outside diameter is 2"3/4. The nozzle is tapered: min OD 1/4", max OD 3/8".
