These do not stay in. They slide out shortly after putting them in. I am going back to plastic combs.The product is well made but the individual ovals that serve as tines were all turned and crooked when I got them. I used jewelry tools to straighten them and then they worked fien.I just wanted plain, simple metal combs. These are it. I like them. Enough said!Mine have just arrived. “Battered” would be the best description. As the manufacturer says, the wire used in them is soft so why on earth were they shoved into a tiny plastic bag then crammed into a box which was way too small before shipping?! Pretty much every comb has bent teeth. Apart from that, they look good and as advertised.These are convenient as bases for decorative hair combs, and are honestly much nicer than plastic combs, But they won’t endure many uses before they fail. The wire feels dead soft, so it bends and warps very easily in ways it really shouldn’t. Next time, I will make my own comb bases with harder and more durable wire. If you need these for single use - like a wedding, they are great. They don’t pull or tear hair.Love it and my combs have turned out wonderfulJust like on pictures and descriptions.Por el precio no están mal pero se deforman facilmente.
