For the money these aren't bad.  They are fairlyw well made, and usefully sturdy (I use them for crystals and stones which are much heavier than your average piece of jewelry), and they have stood up well for my intended usage.  I did receive one tray which had some folds or wrinkles in the base layer of velvet which I was little miffed about, and the reason for them dropping a star.  The selection of different tray capacities is nice to have, and I have at least one of each to cope with different sizes of stones and crystals.

I have customized a couple of them by either chopping out one of the slats that break the main try up into sections, or by twisting them a little to one side (whereupon the internal board material will snap, but the velvet covering stays intact and lets me re-position it slightly).

I would probably rate these as a 9/10 if I could - 4 stars feels a little stingy, but five stars doesn't account for the imperfections in finish which are likely at this price point.  I will definitely be buying more of them as I need them.
