Assorted 3-Pack Matte Flat Lay Claw Clips

My hair is thick and shoulder length. I use claw clips all the time but was interested in trying these flat clips. The smaller ones are good for me to do a partial up-do, but that's it. The large one can hold most of my hair, but I have to twist it really tight and position it just right, otherwise it starts to fall after awhile. I also have to slice it in vertically, as horizontally ends up not holding all of my hair up since it won't close properly.
