I bought these in 2021 and they still work just as well! They’re the perfect size to tuck into shoes, but can be used anywhere. I wear Skechers slip ons all day and another pair all evening when I’m home, and these packs keep them absolutely odor free and dry. It works just as well with socks too. Just let them sit overnight before putting in hamper and they literally have no odor. What a great find!
