Beautiful, Sturdy, Excellent Customer Service!!
Size: 6 Tier, Color: White
Excellent quality item, and beyond outstanding customer service! This jewelry case is very thoughtfully configured, to accommodate various sizes and shapes of jewelry. I purchased this primarily to keep my fine gold chains entangled, and there are numerous velvet hooks, with pockets below to do this. The dividers are not removable, but because there six drawers with difference size choices, it was not an issue, tho some customers may have that question. The watch band bolsters, however, ARE removable. I chose the cream color case with tan/gold interior velvet lining. BUT, the lining, in my view, looks actually to be dusty rose/mauve in color. Not a screaming pink, a bit subtle, but it doesn't look tan as in the photo. Just FYI, in case the interior color is a big deal for you. But the exterior light cream is just as pictured, and is beautiful! Regarding the customer service for this company, I contacted them prior to and after purchase. They responded very quickly, and were clear and articulate in answering my questions / addressing my concerns Thank you!

Good quality and easy gift
Size: 6 Tier, Color: Jelly Pink
This came with some scratches to the metal. Other than that the organization and versatility of this item is amazing. My wife loves it and it cleared up a lot of room for more jewelry. Which could’ve been a mistake for myself lol. I recommend this as a gift for your wife!
