It also uses SnO2 material, whose conductivity is lower in clean air. Its conductivity increases as the concentration of CO gases increases. Features: High quality double panel

The soap does not look like anything in the advertisement picture. The actual appearance looks like a dull kind of brown color. The box looked like it was open before I opened it. It just didn’t appear packaged well and not for sure about the soap quality cause I don’t even know if it’s papaya soap the way it looks.
