Magic Silica Gel

Magic Silica Gel is a semi-transparent glassy crystal used for moisture absorbent. It's lighter than other silica gel. 

When it is moisture free, it appears in Blue colour. As the crystal absorbs moisture, it turns to pink, which means it is saturated & need to be recharged to use again.

How to Recharge : Keep it in sunlight or microwave till it turns to blue.
