They are made of environmental friendly materials including the glue! All of this style items' shortcoming is gem loss, and we glue the gems with AB glue which is the strongest style glue fit for this items, not like others just use solid glue which maybe more fast with much more output not so sturdy, but still not 100% sturdy gems, "So luxury crystal cothes or heels will gem loss, too" we are keep on working to reduce and solve this! And extra gems with glue bottom are made for you to solve it easily! At last if you feel its still good, please not be stingy your good remark! Thank you for your support and god bless you! We love you!
