I am really really sorry for all buyers, i made a big mistake for all my products. for the coupon , i want to write $2, but finally write $12. so each client just give me $0.2 and buy a product. I promise i didn't cheat any one, just really make a mistake. i am a poor girl, i didn't have money to send this products. i hope all dear client can cancel your order, otherwise the aliexpress will close my shop. if you still like this product, pls pay it again, i will give you $2 discount .hope you could kindly forgive my mistake.
