It should be noted that for girls aged 12, if they buy a string, they need to consider whether it is safe and the quality is up to standard. It is recommended to choose regular shops or products operated by certified brands and merchants. At the same time, choose a bracelet suitable for children's size to avoid discomfort caused by being too big or too small. If there are conditions, it is recommended to buy it with your parents.

In addition, although the crystal bracelet has certain ornamental and decorative functions, it also has certain oxidation and wear, and needs regular cleaning and maintenance. Therefore, it is suggested that children should pay attention to the instructions in the instruction manual when buying and wearing crystal bracelets to prolong their service life.
