These Vitchelo moisture absorbers comes in a set of four and came in nicely packed. I use these in my shoes and shoe box.
Running causes sweat to be absorbed in the lining and soles of the shoes. This creates an environment for bacteria. These natural deodorizers bags does not mask odors with a cover-up scent. It actually removes and absorbs the odors and moisture in the shoes.
How it functions is very simple, it pocket seals scents inside and forces all air to pass through the fabric of the bag which has been specially treated with activated charcoal to absorb and remove the odors. They keep your shoes smelling fresh and clean!
I think these natural deodorizers are more effective than sprays and powders that can leave a toxic residue.
Since they are made with charcoal it is advised to keep them out in the sun every few months as these function better when dried well.
