Great man gift
Pattern Name: No Engraving
Hubby bought this. I'm assuming he loves it because it has all his man crap piled on it. He uses it everyday so that's money well spent

Color looks great, material is good quality and fits most of my items. It makes my items look neat and organized. Price is a bit high but worth it in my opinion.

Quite nice and very functional
Size: 7.7" x 7.7" x 1.7", Color: Grey (Metal Silvered), Size: 7.7" x 7.7" x 1.7", Color: Grey (Metal Silvered)
Elegant and substantial - this valet catch all for your night stand or dresser is quite nice and very sophisticated. Sleek and soft brushed suede like material. It was packed well, and is quite nice to keep miscellaneous items corralled together. I’m very pleased and would recommend.
