Review (3/5): Works as a decoration, not very functional.
These beads aren't really "beads" as I think of them, then are thin strip of metal bent into a circular shape. They are quite fragile, and will split in half if opened too far. These were suggested to me by a friend who has her dreads decked out in jewelry and decorations, so I figured she knew what she was talking about. Unfortunately, these are only useful if the hair you are attempting to confine to the metal strip is small in diameter. I have solid beads and rings that can easily fit my hair and stay in place, yet I struggle with these.
I think the issue is that they are too flimsy to hold a large amount of hair in place if it is not already braided. I do not braid my hair, I just use beads to secure it in bunches. I use anything from a 5 mm inner diameter bead to a 17 mm inner diameter bead depending on how much hair I am attempting to secure. Unfortunately, these will not work for what I need them to do, but I believe if your hair is already braided that these can be worn like jewelry, just don't expect them to do any of the securing of your hair.
