Sturdy & we repurchase yearly for Hubby’s refresh
Color: Brown (Rodeo)
This is my hubbys tried and true wallet. He requests this same one every year as a refresh. He wears his 24/7 in his back pocket so it gets discolored but still holds its shape pretty well with a slight bend.

Decent watch if you can buy cheap
Color: Brown/Digital/Brown
Watch is pretty light weight and flimsy feeling. The indiglo is barely there. Nice looking with decent screen and readability. Wouldn't pay much more than $30 for this watch. Cheap Casios outdoo this easily.
