Water crystal granules come in 5 grams packets, 50 grams and 100 grams bags. The bulk granule bags are more economical to purchase.
Water crystal granules look like crushed ice in their dry form. They can thicken the water so that you can distribute decoration objects throughout the water. For example if the wedding/party theme is "fruit", you can distribute slices of lemon, orange or lime inside the vase and the fruit slices will not float to the top of the glass/vase, they will stay where you want them to stay.
You can also mix granules with water beads/cubes to create another beautiful effect.
The thickness of the water can be created by adding more or less water.
After expanding in water, the granules have a bubble look in the glass, the effect can be quite amazingly beautiful!
It is recommended to add clean water gradually to the water crystal granules as they expand slowly as it is hard to remove excess water.
