Love these shirts
Size: 18.5" Neck 36"-37" Sleeve, Color: Persian Blue
Beautiful dark blue color. Soft and well made. Comes out of dryer with minimal wrinkles but not starched looking. A little bit of stretch to it. Does not have the neck extender button. It is a slimmer cut through the waistline for those with wider shoulder but not a bigger belly. It is lightweight especially for FL summers but not thin and see through. Great shirt for work.

Awesome.
Color: Silver Blue Brown
Loved it! I can hardly hear it run, its so quiet! It's very easy to read and looks quite classy. The leather strap has also held up very well to normal wear.

A Great Value for the Time
Color: Rose Gold Black
Beautiful watch that looks far more expensive than it is. The rose gold finish is very attractive, and the black faux leather band goes well with it. It tells time accurately. The only caveat is the date window which is so tiny that it's very difficult to read when not under direct light. I am very pleased with my purchase.

Nice watch!
Color: black/black
This watch was very easy to set and keeps time very well. It looks great with a professional appearance it seems to be well built and the warranty is good. The glass on the first one I got cracked after two months and they are sending me a new one!
