I could use it without trouble in particular. In old cars JIS small washer was used and I was looking for it. JIS small washers seemed not to be handled somewhere else, there was no pack sale at around 300 yen price elsewhere. Monotaro san, it was saved because there was pack selling. To say greedy, it is more nice if you can handle things with chromate specifications as pack items. In automobile-related fields, we would like to arrange bolts, nuts and washers with chromate so we would be happy if you could add it to the product lineup.
