I saw some of these in Asda and they were around £5 for two. I looked on eBay and found three for 99p. These are supposedly equivalent of 20 normal kirby grips / bobby pins.
I seem to loose bobby pins all the time, also the long ones aren't strong enough to hold all my hair up even if I use lots of them. Below are the instructions which came with them.
Not overly helpful, but I have managed to use them for both loose and tight buns, french twists and other random knots and updo's
Really sturdy and I don't feel as if I am about to loose the style. I recommend them to anyone with hair long enough to tie up in to a bun or a twist.
