What are they made of?

They're rubber. Kind of like "crazy balls" when you bounce them they go really high.

I like what Keith said! It is a good weight though a bit bigger than golf ball and as previously stated it is very bouncy! :)

The best answer I can give is "bouncy ball material". T hey're some form of elastic plastic, I guess? They bounce very well.

They're metal. I would have guessed aluminum, but they're ferrous so probably some alloy.

No Sorry don't remember what they are made of. Would be very expensive if sterling. But they do NOT rust or get spots etc on them. Very nice for projects well worth buying.

I don't know what they are made of but they are a really poor quality. Used them twice and they started to break apart. Purchase a set that are made from a solid piece of wood...

They are shiny and thin but I don't have a clue if they are silicone or what they are made of

They're made of plastic or some similar material and are substantial. Definitely NOT metal.

They are made of a very good material, think it's close to rubber, but not sure. It isn't cheap plastic and they hold up very well.

I'm not sure of the exact material, but they're some kind of flexible plastic. Mine warped and distorted after two uses and melted to pieces after three uses, all while drying walnuts and cashews that I'd soaked in salt water.

I don't know what material they are made of but I keep mine out year round and they still look great.

They are either silicon, or silicon-like. Whatever they are made of, they are incredibly pliable, do not dry out , and work extremely well.

They are made of lightweight reinforced polymer. Very strong and reliable! Hope this helps.

They are a very heavy material, ceramic or maybe resin. They are very sturdy and duradurable. I love them!

It doesn't say on the packaging. But I'm guessing they are made from different materials to get the different effects. They are really good.

They are made of plastic. I've been using them for quite a while and they are holding up well, although one was cracked when I received them. I use them to prepare meals and place them in the freezer for later use for my father.

They are made of neoprene and stuffed a spongy foam like material. But more substantial than foam...more like memory foam.

They are made of a heavy metal. Not sure what kind of metal. They are very nice handles and would recommend them to anyone.
