Silicone rubber, yes flexible to a point (sorry for the pun)...The stopper actually can be unscrewed to take apart for cleaning. The top half is rigid plastic, the bottom is flexible to seal the neck of the bottle. The stoppers have held up well and I still recommend them.

I am not sure what they are made of, but they seem to be a blend of a rubberized nylon. They work well, don't slip even when swinging in the hammock, and are durable. I am glad I bought the 2 pairs I did since it makes 'hammocking' easier.

They are not made of rubber and appear to be some type of polyethylene or a like product. They seem sturdy but should be kept away from exhaust pipes as they may tend to smolder or melt.

Yes; a flexible plastic. I broke a number of different plastic ear hooks in less than 2 months. The ear hook has withstood the black-hole (my pocket book).

They are wire and will bend, but stay bent once you do so. These are pretty small, but I find them very useful. I don't think they will hold up to a LOT of heavy scrubbing, though.

They are made of nylon which is narrow but strong. We have been very happy with it.

They are not at all flexible, quite the opposite. They will break even at the slightest bending. How ever there is a solar tape that is much better for what your asking. Unless you can make a large multi sided hexagon shape.

They are plastic. I have had this for a month now with no problems at all. I don't crank down on the fittings when I tighten them however

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 believe them to be rubber. They have a little flex to them unlike hard plastic ones.

The stoppers are reusable. You can easily rinse them off. This is a great wine saver! I give them as gifts.

They are made of a type of plastic. They are very robust as I am using 6 pieces and have had no problems with them.

I have not measured them. However, they are tapered and they fit a milk jug perfectly at the top (largest point) of the stopper.

They are made of a hard rubber like material so should form to any shape. I use many different bottles in them and they grip them all. I like them.

they are made of plastic and have kept their original elasticity for the two months ive had mine. they come in a pack of three with a nice case. i alternate dilators every few nights and use the case to disinfect them with hydrogen peroxide every few days. woodyknows are a great product for relief of my snoring and breathing through my mouth during sleep.....i no longer wake up with dry mouth and get a great nights sleep, not being awakened every two hours by my snoring :)

They are made of strong rubber that holds it's shape, but could also be stretched to hold a large wire. Nice quality!

Some kind of plastic that is pretty rigid . They do not bend or shape to fit teeth. They were much too small for me.
