All little boys size 6. Used but in good condition. No stains or holes. Smoke free home. The size tags have worn off the Batman briefs. They are all the same size and were purchased at the same time. A 4-pack retails for $11.88 from Walmart which is where we purchased them from. This is a great deal! All 21 pairs for 25! Ships same or next day. 4 Mario Cart 4 Spider-Man 4 Minecraft 4 Star Wars 3 Sonic 2 Batman
