Unlike the non-waterproof type, the wheel shaft is located where stainless steel and waterproof paint are painted. This price is over twice, too high. Packing at the time of being sent from it is hidden! I sent it in a box for 4 pieces for 2 items. Because there is neither newspaper paper nor bubble wrap in the box without the gap being closed, it is full of scratches hitting in the box during transportation. The moment I opened the box I felt bad feelings.
