I love the craftsmanship of these books earrings! They are not perfectly symmetrical, and I LOVE it- since it shows that each piece is handmade and unique instead of machine-made. For as big as they look, they are not heavy. My one issue with these earrings is that the piece of metal that secures the earring is very short and if I turn my head quickly, they come flying off. I'm afraid I'll lose one!
