Doesn’t keep accurate time
Color: All black
I bought this for my husband because it said that it self winds but my husband noticed that it didn’t work within the first few days so I thought maybe it was defective so I purchased another one in exchange for the first one but the second one had the same issue. Don’t waste your money on this, it doesn’t work.

My husband bought me this brand of watch for my birthday and it’s so awesome. It looks blingy but not in a bad way. Kinda looks like a Rolex. No battery.I bought him a one and he loves it .

Best Wallet on a budget
Size: One Size, Color: Deep Blue1
Great wallet the material is pretty soft the design makes it look more expensive than it is and the color just seals the deal it’s just the right size and even comes with a mini wallet to hold your cards.
