Is the silver life lock for children hollow or solid?

The hollow lock bag is relatively more atmospheric, and the style of the lock bag is more beautiful. When children wear it, their wearing comfort will not be affected by the overweight silver lock. This is the main reason. In addition, it is recommended that you directly choose products with silver chains. In case of direct contact with children's skin, it is recommended that you choose a product with higher purity, preferably S925, or any enamel material, especially enamel material, which has 100% toxicity. It is cheating consumers to claim that it is non-toxic and high-tech.
