Review (5/5): As close as I have found to my original from the 1990's
I've only had for a few weeks so can't speak to durability but these are the closest match to the size and type I was looking for. I took great lengths with this review since I had such a difficult time finding what I needed. Hope to spare someone else the grief. They are not micro which was too small, true to size 1cm wide and approximately 1.5 cm long.
So far they are holding well (I have long thick hair with bangs). I had one left from a set bought probably 20 years ago which were obviously good quality. They are nearly identical except these do allow for a better grip for your fingers which has to be a feat for such a small clip. Plus I have arthritis in my thumbs, it makes a difference. These are of a different plastic maybe less durable but it's not that thin brittle type plastic. I'm adding pictures to compare. My original is on the left side. So yes I'm pleased with how these clips are designed and if they hold up for longer than 9 months that would be nice.
