A nice valet tray, smaller in size, but with thicker walls / better made than others I've tried
Color: Black
First off, I think the sizing is a bit wrong on this listing. I've used a couple other valet trays of this style, but different brands, and this is my favorite of the there, as well as being the best quality of the bunch. For PU Leather, it's feels good and closer to real leather than usual. Also compared previous similarly styled trays, the sidewalls are thicker than what I was expecting, and the snaps feel tight and of a higher quality.
These ship flat / snap up styled trays will never be as good as the stitched one that you aren't able to flatted, but for $14 it feels like a good value for the quality, and compared the others I've tried from different companies, it is a little smalled, but sincerely feels better made / more durable.
