Nice briefs, worth the price
Size: Medium, Color: White
Briefs feel nice and I love the feel of cotton. Unfortunately they are missing a slot in the crotch that is usually present in these types of briefs.
Size is matching, soft to the touch.

My absolute favorite boxers ever
Size: XX-Large, Color: White
I'm not a man, but I'm a nonbinary person with a big bottom and have tried many quality boxer brands over the years (including the unisex brands). These are my absolute favorite brand of boxers. They're super comfortable. It's taking me a while because I just keep forgetting to stock up but they are replacing all of my other boxers.
