Stock Karma Boxes: Summer — water, sunscreen, socks, sun hats.
Stock Karma Boxes: Winter — knit wool caps, gloves, socks, space blankets, or light blankets rolled up to preserve space in the box.
Stock Karma Boxes: All seasons — one-use hygiene items like toothbrushes/small tubes of toothpaste (no large bottles or multi-item packs), tampons, nonperishable foods preferably in pop-top containers, individual snacks, bars, and ramen. Break apart and package items individually.
Not advised in Karma Boxes: money, books, mini-bottles of alcohol, large bottles or cans, and packages of many pairs of socks (roll up each pair of socks to preserve space). Books belong in Little Free Library boxes rather than Karma Boxes.
