Songmics Slate Gray Travel Jewelry Box
I purchased the slate gray Songmics jewelry box for travel purposes. We take long vacations and have an upcoming 20 day cruise. I wanted a jewelry box that was compact enough to put in my carry-on bag, but still had room to hold a months worth of jewelry, especially to keep my necklaces for tangling. When this arrived, I was pleasantly surprised and the packaging was great, shipped in a sturdy box. so no damage to the jewelry box. The color is a rich gray and the 2 tier box, while small, holds a lot of jewelry. I wanted to purchase the ink black but could not justify paying twice the price of the gray one just to get it in black. It is small enough that it will fit in most any hotel/ship safe so I won't be sitting out in the room anyway. It has a strong magnetic snap that keeps the box from opening while in transit. The one negative for me is that the pierced earring card is so thick that my earrings barely go through to have enough room on the back side the slip the backs on. I may separate the double thick card, realizing it will not look as nice but will be more functional. The bottom half of the box will hold bracelets up to 1 1/4" wide. There is enough room under the earrings card to place pendants, additional earrings, etc. The necklace holder is designed to hold 5 necklaces, but I added one more by going across the top, end to end, to prevent tangling. I also placed smaller hoop earrings in the ring holder which holds them securely. This box held 7 bracelets, 2 of which were wide, 5 rings, 9 necklaces (I placed 3 in the bottom of the box, and had room for 23 pair of earrings (some placed in the ring holder and in the bottom of the bo)! I would buy this again in a heartbeat.
