The watch is beautiful
Color: Two Tone Green
My husband loved it I’m giving it 4 stars because they send me the wrong color. Otherwise, it looked great and definitely worth the price.

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.
