lovely
Color: blue
I love the concept of this book shaped jewelry box. It's got a lot of storage space and the hooks and latches make it usable on it's side like a box or stored vertically like a book on a shelf to save space. I like that it has detailing on the front in gold foil and everything is lined. I got one for myself and one for my mom and we are using both of them and very happy. The necklace pockets are a bit tight so I took manicure scissors and cut them apart to make a larger long pouch to catch chains and that has been working well without compromising the integrity of the box structure.

I love reading and books. This is such a cute idea for my simpler jewelry to be housed. I wish it had a couple more bracelet and necklace holders, but besides that, I’m happy with it!!
