I replace these items every year, so they've been used for about six months overall. (I don't wear the same item every day, so the total wear time for each is short.) The brands are: Uniqlo x 3, Global Work x 1, Muji x 1, and LES MUES x 1. The sizes are a mix of L and those labeled as waist 76-84, 82, and 85. Those who usually wear L size should be able to wear them without any problems. Please purchase only if you understand that these are used items.
