Review on 8 PACKS Charcoal Bags Odor Absorber: Natural, Non-Toxic, Eco-Friendly & Effective Air Purifying Bag 🌿 for Home, Car, Closet, Shoes, Basement – Bamboo Activated Charcoal Air Freshener, Moisture Absorber, and Odor Eliminator by Rachel Guzman

Can't tell exactly what they are for, I've had two large bags in the car for about a month and the smell hasn't changed. This is a 2018 non smoking car but thought it might help freshen up the interior. We have a lot of weed and grass and I thought this product would do a good job of "absorbing" the herb smell, but so far it hasn't. It smells faint, maybe cornstarch, but that's about it.
