Took some time to research this...whew! And this is the best I got: made with polycarbonates or "a synthetic resin in which the polymer units are linked through carbonate groups, including many molding materials and films." I use these for jucing but only for short-term. Mainly for water bottles. Hope this helps.

Pretty certain they are plastic, I can't check as they are all inside a lighting project but I am certain they were not ceramic. However, they work great and I am very happy with them.

Yes! They're made of plastic, but seem very sturdy. They're also easy to clean.

If they're stamped with 2, they're Polyethylene. I assume they're HDPE (high-density) instead of LDPE (low-density). This link will give you more information on the chemicals that can and can't be used with this type of plastic: http://www.cdf1.com/technical%20bulletins/Polyethylene_Chemical_Resistance_Chart.pdf (Just passing this along, as I had to look it up and it took me a while, so I thought I'd share.)

No, they appear to be made of paper, but very sturdy, almost like tightly wound cardboard. They are made in such a way that its very difficult to bend them. I am very pleased with them!

I doubt they are plastic. Pretty thick and dont break when dropped on a tile floor.

I think they are. They are made from heavy plastic and work quite well. No problems.

The box makes no mention regarding your question. Just states that they are made of "super flexible rubber".

They are not rubberized. They are made out of plastic but seem to work well.

They are made of plastic. I wouldn't say it is cheap. I think they are worth the price.

Do you mean "latex" free? If so, yes they are not made of latex. If they were I would not have purchased them as I am allergic to latex.

Yes and they are plastic ... never had any problems with them just remember to break them in and keep clean
