Have been using these large side combs for years but they are not always easy to find.
They're a good colour to blend in unobtrusively with many hair colours & just one is strong enough to hold my mass of fine hair up in a loose bun all day.
I keep extras in my car, desk drawer, gym bag, grocery trolley, etc & they always come in handy - and if I don't particularly want to secure my hair, they're big enough to do a good job of tidying it, too.
The only thing bad about this and it's not the product is that they are so hard to get these days. I can only use the large ones in my hair so I will be cherishing what I have just bought off ebay.
