Primary boxer brief 7-pack. "Primary Mix" colors. Size 4-5. GUC. These were always washed on either "heavy duty" or "sanitary" and dried on "low" or "medium-low" in the dryer. These are the most comfortable and best fitting underwear I have found for my slim child. I initially couldn't find the red pair, so that is why they are in a separate pic. No holes or stains. Smoke-free, dog-friendly, low-scent home.
