These are LUZ e SOMBRA pants. My son wore these, but he's outgrown them, so I'm selling them. The front is clean and undamaged, but there are some snags on the back of the calf area. One of them looks like a small hole when stretched (see image 5, red circle). Please consider this damage when purchasing. He said the waist string was in the way and took it out, so it's missing. Even without the string, they stayed up comfortably without falling down, even on my very slim son. Thank you! ☺︎
