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.

Nice and durable
Color: Black (Trifold)
The trifold is a bit thick, but fits right where my old leather wallet sat. Lots of room for cards and cash.
