Flimsy
Size: 5 Drawers, Color: Beige
I love the design of this but the separators are so flimsy. It’s frustrating storing necklaces when the separators fall down so easily. I can’t even imagine traveling with this. I want to return but for now it’s serving a purpose I guess.

Recommended, exactly what I was looking for
Size: 5 Drawers, Color: Grey
Exactly as described, very practical and great organizer for jewelry. The separators are modular and you can play around with the compartment sizes, which is great. Only small hitch is that the separators are different sizes and some are too long, while others fall down, so still trying to figure out how to use them best.

Good quality
Size: 3 Drawers, Color: Grey
Wanted something to hold my necklaces that I did not have to fasten and then unfasten when I was ready to wear. Tried several but sent back. Although pricy, best choice and works well. Very good quality!
