I had some jewelry I wanted to gift to mt niece and needed something to send it in. This was a lovely little box, great for travel or sending jewelry in. It was well made, had ample space for different pieces of jewelry and made a really nice little presentation box, imo. It's something she can use regularly on for a trip. I liked it
