Quality is good.
They are accurate to the seller’s photos however they are made in a way that their natural orientation when on your glasses isn’t straight. You’ll be lucky that in their dangling, rotating movement that the skull part is facing the correct way. The charm part dangles very violently so it’s reccomended to have it tucked back by your ear. The clear elastic part that is attached to your glasses aren’t very tight, so it may fall off your glasses or move across the side of your frames through your movement.
