Superdrug Non-Slip Hair Claw 1 Large Brown

I had high hopes for these clips, they're a great size and I love the non-slip bits. Sadly the spring is really weak so it won't hold my thick hair.

I bought 2 of these and 1 of them tuned up broke and they are not the size they say on the page in the product description. I needed a large claw grip and this looked perfect until I received it, 16.5 cms it is supposed to be and its more like 10 cms...
