This is a HK Man boxer brief (trunks). HK stands for Heidi Klum and these are 5-6 years old. She marketed her men's line through Bendon, a New Zealand-based underwear shop. These are all white with a wide covered elastic waistband and "HK MAN" on a tag sewn in front. There is no fly, but there is a double-fabric front panel. They are made in China of 95% high tech cotton and 5% elastane, and are super comfortable. Refer to the photos or ask questions for more details. Storage is pet-free and smoke-free.
