KHK's gear has been used for a long time. Because the current parts trading company handles the parts of other manufacturers until delivery of KHK's gear for vendor change, delivery time will be required. Because it arrives in almost the same number of days as those of Monotaro. Purchased about 4 sets drawn by price. I happened to buy it separately in this time but it was able to purchase the same thing quite cheaply as it overlaps the special price on Saturdays and Sundays special deals campaign. As soon as possible to arrive one day earlier we will ship on Saturday and Sunday orders on Friday morning so we will be saved for processing, but thank you.
