Three pen pockets on the outside, a perforated tool (cellophane tape etc.) is hung on the decorative belt. You can also prevent metal sounds if you lock the locker key etc. that the size of the outer pocket also dropped to the key ring just inside the pocket. Iphone also uses a large rubber cover for the larger body part
I firmly enter.
Regretfully it is desirable for the buckle part of the belt to pass through the small hole tool so that it will hit the pen and hit the pen while walking so that the buckle will be on the opposite side.
