Nice watch!
A very nice looking piece with good size and a lot of weight. One negative, the band is really hard to resize as you really have to work at it! Once done, you have a good watch!

Bold & dressy
This watch is basic & bold, it is larger than I had expected but has a finished look without being too dressy. Casio has a great track record for reliability. Good for using daily and fits upscale at the same time. I really like it.

A nice, comfortable t-shirt with a bit higher moc neck
Size: Small, Color: White
I wear tee shirts a lot, but, because I need something a little warmer at times I wondered if such a thing as a moc-neck tee existed. This shirt is soft and comfortable, not tight but more tee shirt- like in fit.
