Because genuine one piece is 5000 yen, purchase while thinking that it is useless even if this amount is not good. However, it seems to be pretty solid and not appearing to disengage. It looks like aluminum foil with 5 holes look pretty well.
Considering purchasing a genuine product for 5000 yen per piece, 4 items can be bad for this amount of money, it can not be helped, purchased with a feeling much. I was watching every morning when it will be out, but it is securely fixed and can not come off. The appearance also looks good and you can see it as a 5 hole aluminum foil.
