Thank you for your help. I ordered several items on the same day with this product on June 10. However, No. 34662266 Sekisui Chemical Co., Ltd. I wanted to use 15 cheeses dedicated to HI water supply at the same time, so I got an order as input for No. 34662266 after June 20 on sequential shipment. Actually, on June 21, those who wanted to use had decided to relocate and wanted to improve manufacturing facilities by relocation. Since I can not work without this product, I have just purchased it at a wholesale store in the facility. I received a very inconvenient comment because other goods arrived the next day.
