Sometimes mildew is very annoying. My mother had some new handbags that she never used. She put those handbags inside her wardrobe for couple months, but when she likes to use one of those handbags, there is mildew inside all those bags. In fact, those bags cost millions, and cannot be used anymore. So she asks me to buy antibacterial products to prevent mildew for her new handbags. I go to a supermarket near my home, and I found Swan Naphthalene Ball. Swan Naphthalene Ball is white crystalline strong-smelling hydrocarbon made from coal tar or petroleum and used in organic synthesis and as a fumigant in mothballs. It is very good to protect leather articles, handbags, shoes, etc from mildew. They are also safe for all clothing materials including wood, and would not do any damage or even dirty my clothes. To use it, I simply put some Swan Balls without any wrapper inside those handbags and at each side of the wardrobe. The result is good. Now my wardrobe is free from mildew. The price is not expensive. It only cost $1.1 for 300gr.
