Question: Are these seamless so they can be easily cleaned?
Document: Flows freely and easily cleaned. Works well with salt and oils. Three sizes fits most small kitchen applications. I do recommend.
Nice, heavy gauge funnels. They are small so be sure that is what you want before you order. Great for filling up salt shakers and small bottles. Has a ring device keeping them all three together. The have a polished finish which is easily cleaned.
These are so handy, dishwasher safe and store easily and stack able. Not sure what else to say, these are great!
Great sizes, stainless, very nice. They fit easily in drawer. I will get a lot of use out of these.
These fit nicely into my essential oil bottles for mixing and refilling oils. They come on a ring that hinges open easily.
Well constructed, have used often already. Now I need one larger, these are on the small end. They are easily stored in a drawer.
Excellent funnels, fit into the mouths of small bottles I use for homemade bath products. Easily washable in the dishwasher
I love the fact they are Stainless steel, as they clean up easily and do not hold any fragrances of the items I poured. Makes so there is no cross contamination.
Not much to go wrong here unless they start to rust. My only complaint is that the ring that holds them together is a bit flimsy and comes open too easily. Aside from that perfect.
This set is easily stored & works well with preparing liquid or dry ingredients. For liquid, you may have to lift it slightly if the movement slows to allow air flow. They're durable and clean easily.
Answer: I am not certain.  The cones are seamless.  But the stems may be joined to the cones.  The seam is hard to see, that is why I say I am uncertain.   If I were a betting person I would be a dollar there is a seam between the spouts and the cones.  But is is very well finished.I think these are a great value, and very well made.  The quality is quite excellent for the price asked.
