It is a highly porous but solid mineral which has a very good bond for water molecules.
Imagine, the surface area of 5 or 6 teaspoon of silica gel is equivalent to a standard-sized soccer field!
And that is why it is used as a desiccant to keep things dry.
Is Silica gel harmful?
Silica gel is transparent and harmless, but sometimes, you may see they mixed with red or blue beads which

of the humidity, and these two substances are not safe for humans, so please do not have direct contact to those substances.
Our product do not contain the above mentioned harmful substances; instead, we provide separate indicator cards for the indication.

What are the basic hints for using Silica Gel?
1) In terms of "sealed enviroment", it refers to containers, jars, boxes or even heavy duty plastic bags with good and proper sealing. We can call this as" small climate control".
2)This is the most important part. If the sealing is not sufficient, it will lost the significance as when the fresh air penatrate through , your valuables may still get damaged by the moistures.
3)Check the status of the silica gel after the initial deployment after a few weeks. Replace or regeneratethe silica gel if necessary, after that, you can check again every 6 months or even longer, as long as the structure or sealing did not get damaged.
