I replace these items every year, so everything was purchased within the last year (though some items may be older). I don't wear the same items every day, so the total wear time for each is quite short. The brands are: Uniqlo x 3, Global Work x 1, Muji x 1, and LES MUES x 1. 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 these without issue. Please purchase only if you understand these are used items.
