These don’t have a wire in them they only have the clasps so they snap together which isn’t what the picture is and not what I wanted. Returning them!I have used these rollers for years and love them. I prefer the 1/4" (lavender) for tight control and the 3/4' (yellow), and the unless you have really long hair, don't go with the 10-in long ones. If you're budget-conscious though, support your local beauty supply or buy directly from Annie Inc where the price is about 25-30% lower.I ordered a set for myself and each of my three daughters for Christmas and they were a hit! My girls are 8,11,13 and they are each able to use these rollers by themselves because they are so easy to use! It's easy to get great results with them and the great thing is that the curls (or waves, whichever you prefer) last all day! I absolutely love them and recommend them to anyone needing an easy way to style their hair. I can put them in and let them set while I put my make up on and get dressed...then I'm all done!This was kind of a last minute idea for a gift and so I was worried that I wouldn't receive them on time but they came on time and made me so very happy!My hair is past my waist. Therefore, most flexi rods are too short. This is the perfect size. Only complaint is the smell. You definitely need to let them air out for a at least a week. But that's the case with any that I have purchased and not only this brand.I bought the purple ones. These do not have wire in them! So you can’t mold them to properly close them around your hair after you roll it. They do have a pin at the end that snaps into the other side as a closure, but it’s just a giant ring and my hair slips right out. I did like the size, but I can’t use them. For reference, I have mostly straight Caucasian hair, and have used other flexi-rods (with inner wires) with success.I needed some foam rollers but had no access to a beauty supply store so I got these, they worked well and knew the assignment!My hair turned out great.My hair is VERY thin and VERY naturally straight; nothing ever curls my hair, not even a curling iron. I left these in for maybe an hour when my hair was about 90% dry. After I took them out it looked a little weird but of course after flipping my hair a few times the curls were perfect. These curls lasted about four hours without hairspray, which is a very long time considering how long I left the rods in. Because the rods I received were a lot thinner than the others, the curls were a little tighter, but not too much. For all of my thin hair I had to use 10 of these rods. Perfect!They're okay one of the ends fell off.
