I had a pendant custom made, sourced a chain separately, needed a box for the whole package.  This one caught my eye.

As a box, it's decent quality and construction.  Not luxurious but nice feel and solid hinge.  And the light works; when you open it a LED illuminates the jewelry.

But otherwise the light is kinda gimmicky.  Mine was a little bent off aim but easily corrected.  The color temperature of this light is a very cool white, not a warm white.  That's fine for all-silver pieces but if you have other colors it washes it out.  Ultimately a nice idea but not much of a value-add.

So, if you like this box because you like this box and the light is just an extra neat feature, go for it.  But if you want this strictly for the built-in light functionality, you'll get it but it might be a little disappointing.
