How to preserve the gel?

Answer: avoid direct sunlight when saving
Because the gel has the characteristic of being hardened by ultraviolet rays, it is very important to keep it in a cool place where sunlight cannot be directly exposed. Moreover, if the bottle’s body is put down and preserved, the gel may leak from the gap, so it is necessary to keep the bottle body upright. Also, the gel bottle mouth will be hardened and the lid cannot be opened. Therefore, after using the gel, use the gel scavenger to wipe off the gel at the edge of the bottle mouth.
