Hello loc nguyen, the accessories are only available when order size is US$50 or over.
You can buy item(s) separately, but the unit price will be high (because the international shipping cost), please submit ticket (with product link & request) to our Support Center and let my teammates help you directly. n_n

Hello, does your ear have to be pierced to wear this? Or is it a clip on?
