Review on Gonzo Bamboo Charcoal - 6 Extra Small Bags 10g - Natural 🎋 Odor Eliminator for Home, Drawers, Pets, Gym Bag – Air Freshener with Purifying Charcoal by Christine Radcliffe

I've only had these for two weeks but I would definitely recommend them as they have completely eliminated all odors in all my running/gym rooms. Shoes! I leave them in my sneakers overnight and take them out when I need shoes. Haven't tried leaving backpacks in the sun to "charge" yet as they don't seem to cling to odors that easily, but I'm sure for a new use it will actually work.
