are these cups hard plastic or do they flex?

These are hard plastic cups. They flex a little bit( very little bit), they will break if you flex it too much.

I guess you'd call them a hard plastic, they are smooth and thin and not noticeable - I had to look for them to answer your question.

Yes, I believe they are hard plastic. I attached a small piece of slip resistant fabric, so that it wouldn't slide around our quartz countertop.

They are rigid plastic. Moreover, the fan speed isn't as good as what I'd expected.

They are black plastic, but I wouldn't call them 'cheap' just because I have seen much thinner and 'floppier' versions. These are inexpensive and are a bit super-sized as well to accommodate multiple sized cups. I screwed holes in mine and mounted them in a Mardi Gras float, so that each rider would have a place for their drink. They survived their first carnival quite well!

yes, they have a hard black rubber backing and are flexible but fairly stiff.

They are a soft plastic and you can squeeze them a little. Not are hard as my other set of Cuisinart bowls - I did have one of those crack. I have not had any problem with them. One of the things I like about this set is that they don't collect water in the bottem rim when upside down in the dishwasher like my other Cuisinart bowls do.

They are able to be bent. I would say they are a soft plastic. I bought them for my 2 year old grandson and he uses them for soccer and building a fort.

The ones I got were rigid, they had a tiny bit of flex to it but nothing too soft.

Yep - they are plastic! I would add that they are a sturdy plastic, probably crack-resistant. My kiddos have dropped them to the floor several times and they did not split or break.

They are hard plastic. Not rubbery at all. My daughter likes to chew on them and they've shown no sign of wear.

I don't have the packaging to tell you exactly what they are made of, but they are definitely flexible plastic. My granddaughter loves them.

They are made of a hard plastic. They have a glossy finish inside and a matte finish outside. They have a rubber non-slip handle. They do not have a recycle number on the underside of the cup.

No, the cups are semi rigid. The straw is very rigid but some here say they just use disposable ones as well.

They are a hard plastic. Been using for a few months and seem to be pretty decent quality. The blender still rocks!

They are flexible. You shouldn't have any problems.. I was very happy with this purchase

They are soft and bendable. They are large around as well as tall, so they don't fit in all glasses/cups that have pre-made holes.
