While I do my best to make sure that my jewelry is made with care and is durable, it's not intended to be used by children under the age of 3, and such could pose a choking hazard.
I also recommend not wearing jewelry in situations that may cause it to become tangled, such as sports or other rigorous activity, which may result in breakage or injury to the wearer. Long dangling earrings, necklaces, and hair sticks are the most likely to pose these types of risks, however wearers should be cautious with any jewelry in these types of situations.
Much of my jewelry is made using glass beads and as such, may have a tendency to break or crack, and though there shouldn't be any problems with breakage with normal use, they should be inspected by the wearer regularly to ensure damage such as fractures or chips in the glass haven't occurred.
